In Preferences > User Interface, you can set Decimal Places for Units Types in the millimeter box to anything from 0 to 6.
Note that this sets the display rounding but internally the precision is always the maximum provided by the app, around 8 dp.

Haha I feel dumb now lol.
 
You want to click on the icon that looks like a crosshair it's tooltip should say "Show Rotation Center".
 
Then you can drag that control point wherever you want to adjust the rotation handle

I found out how it works. Click on the freehand selection on the left and select the polygonal field at the top (red arrows). Then the shift key does not have to be pressed and moving the image with the space key is possible. What is still missing is the automatic move, if one comes to the edge of the picture.

have been a photoshop devotee for years and am trying to move my entire folio of work into Affinity.
 
the one issue I am having is finding the equivalent of the polygonal lasso tool that is in Photoshop for trimming photos/layers? A lot of my work requires scanning in existing drawings and then trimming around them to give them a clean edge. I have been able to do this using the masking tools but cannot for the life of me figure out how to mask a clean, straight edge? I am probably being a bit thick but am really struggling to find a solution. Any tips would be appreciated.
 
As I cannot seem to articulate what I am trying to say, I have taken some crude screenshots of what I mean and attached them,

How strange that we have two different tools to accomplish the exact same thing (rounded corners), and they're completely incompatible with each other.

Thank you for the tip.  There is one caveat, however.  Your tip does not work on objects which already have rounded corners (and I don't mean "baked" corners either).  Try it.  Sketch a rectangle.  Choose the "Corner" popup in the info bar atop your window and choose Rounded.  Then choose the Corner tool and try your tip -- you can't.  This caveat matters little when you are designing your own rects.  But if you receive an AD document from someone else with objects that already have rounded corners, you cannot round multiple corners via your tip.  In Illustrator though, this is no problem at all (unless corners are baked).

To round individual corners one need only untick "Single radius" in the info bar at the top of the window.  But how do we select 2 or 3 corners and round them at the same time (to be the same radius)?  This can be easily done in Illustrator.
 
Thank you.

Agreed, and once they are on that subject, they can add to them also some load/save features as SmartCurves offered years ago.

I couldn't agreee more, all three (white/black/midgrey dropper)   are essential tools that I would expect AP to have, I use them all the time in PS, both for photographic images and for scanned illustrations, like line sketches. They are invaluable and it's missing features like this that stops me from abandoning Adobe and PS.

I started this thread 3 years ago.  It has been supported by numerous people as you can easily see.  And yet, not a single thing has been done by Serif to add the dropper icon akin to what's in Photoshop.  I've made numerous other suggestions in this forum through the years -- nearly all of which have fallen on deaf ears.  I want to know why.  (And please don't give me "no time due to work on Affinity Publisher" as an excuse.)
At the end of the day, it's not the fiddly workarounds people flock to but rather the familiar.  
Serif, please add the dropper tool to Affinity Photo today.  Adding more helps like that to Photoshop users is the fast track to getting more of them to switch to Affinity Photo.  Three years is already much too long to wait.  Do it to humor me.  Do it to show you actually care about customer feedback.  Do it for your own reasons.  Just do it. Do it today.

I just tried it.  I must say, that "pull-string" approach to drawing is rather intriguing.  However, it is no substitute for a tool or menu command that smooths/simplifies paths as can easily be done in Illustrator.  Why?  For reasons I've already stated.  Sometimes you want to REPURPOSE EXISTING ART.  Your new tool only helps when CREATING NEW ART.  I want the means to open an old file I created or a file somebody sent me or a file I downloaded from the net and then simply the paths, akin to what Illustrator can do.
 
I hope that's clear!

LOL.  I am NOT "wrong."  I do know the English language natively, so perhaps there is a translation error on your part. 🙂  "For years" & "6 years" are pretty much one and the same, my friend.  It really is a long time in computer years.
With that said, it doesn't matter if Adobe has been around longer than Serif.  "Why not," you ask?  Quite simply because we are NOT asking Serif to recreate EVERY SINGLE FEATURE of Adobe apps.  You got upset and jumped to conclusions in thinking that was being asked of me and others like me.  That was not and is not what is being asked.  As such, any comparison between those 6 years and Adobe's app existence since the 1980's (even before Adobe acquired those apps), is largely irrelevant because we are talking about a simple few features here and there.  They are key features though, which is why I keep pounding on them as people come across these ancient, spider-web laden threads originally started by me.  
Based on what you wrote, I seriously doubt that if I stopped what you call "whining" that you would respond in kind and suddenly stop bashing your fellow Affinity lovers over their strong persistence in asking for a few new features.  Let's face it. We are in the same boat whether you like it or not.  The fact we all have purchased and use Affinity apps puts us in that boat.  Some of us have different needs though.  It would be great if you could be more open-minded about that, but I realize some folks prefer to worship the status quo and avoid thinking beyond the box of features they already have.  But here's the thing...  If the existing feature set pleases you, great!  I'm happy for you.  I really am.  But please don't bat the rest of us over the head for asking for more -- even during those times we ask for it repeatedly and even provocatively.  
If ultimately Serif does add more features that tickle Adobe users pink and bring even more them over to Affinity apps, those new features won't IN ANY WAY transform Affinity apps into the Adobe apps you seem to dread.  Again, we're talking a few features here and there.  That's it in a nutshell.

This is probably the most important function for me to be able to ditch PS. Please implement something like this in AP!This is probably the most important function for me to be able to ditch PS. Please implement something like this in AP!

Where is the Set White Point in Affinity Photo (AP)?
 
Please note that I've been using the AP beta and recently I purchased the app via MAS.  I am trying to transition from Photoshop but I am faced with a learning curve.
 
In Photoshop, I hit CMD-M to bring up the Curves dialog and then click the rightmost dropper icon ("Sample in image to set white point") and click on the light parts of my image.  That adjusts the white balance and the white point beautifully.  I use this all the time on the white parts of scanned images to make sure white is 100% white.
 
I want to do the same thing in AP, but no such feature exists in the AP Curves dialog that I can see.  And when I type "Set White Point" or even "white point" in the Help menu Search field, nothing relevant appears.
 
How do I accomplish this in AP?  Again, I want a drop tool (or similar) that allows me to click on light areas of the image and set those parts to pure white.
 
If there is such a feature in AP, please note that Photoshop allows me to press the Option key after I click the White Point dropper to see areas that are still dark.  That is very convenient to allow me to see where else I should click the dropper to make sure all the white areas are pure white, not leaving any light gray patches anywhere.  Does AP have this?
 
Thanks.

I disagree profoundly with most of the above 3 statements, although the second half of the third sentence above does seem like an admission of sympathy toward your fellow Affinity app users, which I sincerely very humbly appreciate. But I must refute the other statements as follows...
Is it “respectful” to boldly say that you "don't like" your fellow Affinity users repeatedly requesting something you yourself do not find necessary? (If one answers “yes“ to that question, then one must recant and admit that users asking for features which resembles PS must also be deemed "respectful." But if one answer is “no“ to that question, then one’s own statement about "disrespect" suddenly becomes null and void.)
 I personally feel we give Serif our biggest "respect" when we pay them money for their software.  If one tries to argue with me saying, "Yeah, but we don't pay much," I shall boldly refute such by saying, "that is the fault of Serif, not you or I!"  What if Serif approached us and said, "would you pay us a bit more for some of the features you have been requesting?"  I have little doubt most users who want those features would say YES!  And yet, Serif has never given us such an opportunity.  They don't even engage us in the forums either, unlike other developers do.  So all is left is for us to express our pain and suffering as best as we can in this forum, in hopes that someone in a power position at Serif will one day read what we write, then kick the engineers in the pants to get cracking on it!  Yes, I can be provocative in what I write, but so was Steve Jobs with his people.  Sometimes you have to be a bit forthright to clear stubbornness out of the way and make a little progress.  Some will hate you for that, but many others will love you for the end result.
Next, you said you are 100% sure about Serif's intentions.  That is a bold statement. Yet you do not work for Serif as per your admission of being an "outsider."  Again, I appreciate your saying "the balance is not right," as that plainly justifies all I have written to date.  But the fact remains you made a very big assumption on the part of Serif which you really cannot be 100% sure about.  But let's analyze that by considering just how many YEARS it has been since Affinity apps first came out...
What headway has Serif made in dethroning the Adobe beast in all these years?  Answer: Hardly any at all.  Is there any clear evidence Affinity app users are growing by leaps and bounds?  No, I cannot see that.
That is not the fault of price though.  That is not the fault of NOT having a horrid subscription model.  Serif is brilliant in having made those decisions!  I sing the name of Serif unto the highest heavens for that!  That is why I am still here, my friends! I really do love Serif's creations.  I just find them lacking in some areas and everything within my being screams out at me to voice those deficiencies.
So what then is the problem with growing our user base?  Is it that people refuse to use any software without the holy "Adobe" named stamped upon it?  Doubtful.  Is it that people want to continuing working as they always have, with a familiar set of tools, yet without that horrid and detestable subscription model?  I cannot speak for everyone here, but in my own case, that is a resounding YES!  And yet, for some users of Adobe apps, the feature set of Affinity apps is still incomplete.  
Again, it's not like Affinity apps came out yesterday, last week or even last year.  These apps have been around FOR YEARS, and yet the feature set is not advancing in such a way to break more Adobe users away from the very subscription model they hate — they do hate it, if they admit the truth.  Therefore, I must logically conclude that Serif is trying to forge its own path without thinking much of Adobe users, merely hoping that Affinity becomes so popular in the market that popularity alone will magnetically pull Adobe users toward Affinity apps.  But if that is indeed the way they think (and I am not "100%" sure about that), Serif is deliberately overlooking the fact that to become big in this market, you must pull users away from Adobe.  How does one pull users away from Adobe, you ask?  Answer: COMPELLING FEATURES!  That is the very heart of this thread and my other feature request threads.
All said...
Serif, please stop dilly-dallying and just implement "Set White Point, Photoshop-style."  We want it.  You know it would be great.  Now be like Nike and JUST DO IT.
THANK YOU!

Better not talk about it too loudly or @fde101 will be telling you that "your expectations are not in line with reality." 🙂 
The sad reality is that Serif really doesn't care.  If they did, it would have been implemented by now or they would have cared enough to have one person from their company actually read this forum and chime in now and then.  I am in the forums of other software where it's a night and day difference.  Some developers care, while others don't.

2021 here, still looking for this feature first requested by OP in 2015. 

I posted the following thread 3 years ago but not a single person until today advised me to post that topic in this thread, claiming that no one from Serif diligently reads this forum such that my post was sure to have been overlooked these 3 years.  Seems odd to me, but fine.  Here it is:
 
I would advise Serif to just move that thread into this thread.  I would prefer that since I don't want to lose all the supportive posts in that thread.  For truly, it is more than just me who wants that dropper tool added to Affinity Photo.
 
Thanks.

In the midst of a dark and dreary pandemic, I certainly appreciate a good laugh.
The folk at Affinity knowing the word "soon"!  LOL!

Another user moving from PS after a number of years restoring water damaged and color shifted images.
Being able to find the location and set accurate white, black and midtone points was an essential part of the process, made even more useful by being able to set the white picker to less than 255 and the black above 0. This gave a safety margin should it be necessary during the rest of the restore, reducing the risk of accidental clipping.
Another vote for it or a simple equivalent addition to AP

Well, it wasn’t to be. Maybe 2021? Still hoping...

Yeah, setting the black and white point is critical for anyone wanting to PRINT especially photographers making fine art inkjet (archival pigment) prints.If this feature existed in AF I would ditch PS for good in my lab. But at this point, without the ability to properly set WP and BP by the numbers, it's not possible to maintain a professional digital print workflow. PLEASE get this sorted out.  SOON?
 

That pales in comparison to what Steve Jobs would tell them.  I am an old softy in comparison.  But they really do need a Steve Jobsian style tongue lashing.  NO EXCUSES!
I refuse to sympathize with engineers I've never met.  I can only judge them by what they deliver and what they don't.  
Lastly, I absolutely POSITIVELY refuse to "bear in mind how LONG THIS TAKES."  This has taken YEARS and still nothing.  The more people tell me to be patience, the more upset I become.  I've you want to calm me and the rest of the disgruntled users down, you need to start sympathizing with us rather than the engineers you too have never met.  And if those engineers wish to defend themselves, the forum is here, waiting for them.
