FWIW, on my Mac the files in these temp folders for each of the Affinity apps usually are automatically emptied whenever I quit the app but occasionally one or more are not. I have never figured out why -- it doesn't seem to have anything to do with the app crashing or anything else I can identify. But even if the app is running, as long as there are no open documents in it, I have never seen any problems with it if I delete any/all the files in that folder. But keep in mind this is a 'use at your own risk' thing, not a recommendation for you to do it.

I don't understand why that would be needed or wanted. First, if it is the Clear Menu item on the File > Open Recent submenu that we are talking about, it is next to the last item on it, so assuming there are at least a few recents shown users have to move the pointer down to it to choose it, which to me seems unlikely to be done by accident. I Do use the "More..." item at the bottom frequently, so to avoid even having to open the menu, I created a keyboard shortcut for that (Option-O on my Mac), so for me the chances of hitting clear by accident are basically zero. But more to the point, even if it does get cleared by accident, it should be easy enough in Finder on Macs to search for files with the *.afdesign extension, sort by date, & choose any number of the more recent ones to open. I assume something similar can be done in Windows. So if that is true, then it should be easy enogh to open all the desired recent ones, use Close All to close them all in one step, & thus repopulate that menu.

Do you mean the menu item File > Open Recent > Clear Menu or something else? I have hundreds of AD files on my Mac, so it would be impractical to list them all in one "Open Recent" list. But on Macs there are Finder options (so-called Smart Folders) that can list all of them, or all that meet certain criteria like size, date range, etc., which is a far more flexible & to me useful way to find my AD files. I am not sy=ure but I assume there is something similar in Windows. Anyway, there is a dedicated Feature Requests & Feedback forum for things like this, so please post your requests there, not here in Questions where the powers that be are not likely to see them.

Could you explain more about how specifically it 'wanted' to do that, & what other files were in the iCloud folder you wanted to save it to? Something seems very odd about that but maybe I'm missing something obvious....

It is the unique Apple developer ID assigned to Serif/Affinity, signifying that the company is member of the Apple Developer Program. If you look in ~/Library/Group Containers you may see other similar ones like 4R6749AYRE for Pixelmator or other apps you bought.

On Macs, it is named "Reset Most Recent Documents" & it is possible to deactivate all other reset options except that one, so it is minimally disruptive. @martenf, have you tried that; or at least tried starting APub with the CTRL key held down to display the resets options? Some users have trouble getting that window to display, but once you do, you can click "Cancel" to reset nothing, so maybe see if that works.

have you tried the CMD+L & CMD+R keyboard shortcuts?

Well, no, I can't "open" the tiff in Finder I think what @RNKLN was asking about is you can rotate images in Finder without opening them. One way is to use CMD + L or CMD + R to rotate in 90° steps. You can also use Finder's Quick Look to rotate the image via the small rotate CCW button in the header, next to the annotate button. Try it with this simple Pointer.tiff file to see how it works.

What issues? Do you mean after using "New" to create a selection, switching to "Add" does not add to the selection? If so, that works fine for me on my Mac. Also, using hardware acceleration does not cause any issues with this or any other tool for me, so again I wonder what issues you are talking about. Switching to AD would not work for this because its Pen Tool does not have the Selection option to convert a vector path to a selection (or to a Mask) like AP's Pen Tool does.

No, it because the TIFF RGB 16-bit preset with Bilinear resampling already exists -- it is built into the app, & can not be duplicated, deleted, or renamed. So try some other export option, like just for testing TIFF RGB 16-bit with Bicubic resampling, named "Test" or whatever. That will allow you to Create a new preset, & once created you can rename or delete it.

As I said, the name of that tool is the Freehand Selection Tool, & the selection Type: is Polygonal. I also asked you to say what Mode: you have chosen, so could you either say what it is or provide a slightly wider screenshot showing that?

Works for me & uses US English, so it should work for others using any supported language. 👍

As @h_d mentioned, you probably have disabled the "Show tools" option on the View menu. FWIW, in Affinity-speak this is not called a toolbar, nor is it a dropdown, which is the term used for menus that open (drop down) when clicked on them. In Affinity-speak this is simply called the Tools panel, while the panels on the right (& optionally on the left) or floating are called Studio panels, & can be grouped, presets created for them, & so on.

There is no tool named "polygonal selection tool,' so do you mean the Type: option named "Polygonal" of the Freehand Selection Tool or something else? If it is that tool, what Mode: does the context toolbar for it show? What other options for it does the context toolbar show?

So what, if anything, is left that you need help sorting out about the UI? Tip: once everything is the way you would like it, use the Window > Studio > Add Preset menu item to create a preset for that layout so you can return to it at any time. Also, spending a little time reviewing the help topics & video tutorials for the app will show you all kinds of possibilities you might otherwise overlook that will help you work more quickly, confidently, & efficiently.
