On Windows the answer is PDF-XChange editor. In the past I used to work with Acrobat Pro to create interactive fillable forms, but PDF-Xchange Editor is actually more usable than the "original" for this type of work. And full Javascript support.
I am a firm believer in a two-step process: design the document in a dedicated design/publishing app, then add the interactivity and form fields in a dedicated PDF form builder. The reason is simple: even if the design app supports inserting form fields and the like, it could never hope to compete with a specialist PDF form editor.
As for ePub export in Publisher: I hope for the best, but harbour no expectations at all. Besides, interactive FXL ePub files only work properly in Apple's ecosystem (iBooks reader), while on Windows, Linux, and Android such books break, because no good ePub reader exists which supports these. InDesign's FXL interactive ePub files are near to worthless to 90% of users.
Flowing ePub 2 output is however quite useful to have. But that means the output would differ completely compared to what is seen in Publisher: flowing ePubs' contents flow and adjust according to the screen size and user settings. Therefore it is debatable how useful such output would be in Publisher. To be honest, I never used InDesign's non-FXL epub export and instead opted to export text and import into Jutoh or Sigil. (Far more controllable and reliable in my experience.)
I would like to see plain old structured semantic html output from Publisher (no fancy CSS styling required but linked images would be with image quality export option), which is easily converted to flowing epubs with any of the above mentioned tools or even PanDoc.
Epub FXL output would be interesting to have once the reader software situation on OS platforms outside of Apple is resolved. But I am not holding my breath: I have been waiting for years now, and it only got worse since the demise of Readium on Chrome  due to Google's actions.
 

Hey
Has there been any idea on whether we can get this feature at some point? I'd really like to not have to sub to adobe for indesign just for this one thing.

Here is a poem which attempts to convey some of the challenges faced by caring for someone a relative with dementia. It is an experimental layout in Affinity Publisher.
I found the layer effect emboss quite useful for adding interest to the page. Particularly using the invert option to create something unexpected. Adding 3D to the text also helped the output look far more interesting.

First image is the original image with only a small bit of sharpening, second is the same image after a bit of luminance masking and some HSL adjustments. Topped it off with a bit of dodging and burning. Not a great subject, but a good bit of practice now that I fixed the corruptied tablet drivers installed by Micro$loth's update about a year ago.
Thought my tablet just wouldn't work with affinity . . .  went to Huion and got latest drivers, turned off "Support TabletPC" which corrupted driver would not allow.. Works perfectly now.

Thanks. I didn't crop it more because I thought it would have moved it out of context (to me anyhow). Love patterns, just don't work with them much.
Thanks. Some of the ones I had that spring even had turquoise, cyan, and blue in them. They can be quite striking --- and then when you add just a touch of vibrance and saturation they can get wild looking really fast.

@Smee Again, a nice photo. The Turkeytail fungus is extremely variable ranging from dull grey to rich orange. Your bunch shows the range in the cluster! Your edit has brought out the orange nicely.

Tiny orchid like flower . . . on a U.S. penny for scale. Once more, auto-out-of-focus keeps this from being as sharp as I'd like. The penny is approximately 3/4" in diameter (I believe that makes it about 2cm to you folks across the pond) and the width of the flower is less than 5mm.
The most amazing part of this photo is that I actually saw it while walking. The dead mosquito on the right seems to have been stuck by some sort of sap.

According to the US Mint Coin Specifications page, it’s exactly 3/4".
Again according to the above page, it’s 19.05 mm (or 1.905 cm, if you prefer).

Like playing with macro images, just not into expensive cameras. Took this at about 9:00 on a Sunday morning. Full sunlight, but the heavy growth behind this soon to be 3 headed flower literally looked black with very little adjusting. The L340 is completely autofocus --- or sometimes "auto-out-of-focus" might be a better description of this camera's ability.
May post a few more of my macro images. I love looking for the unusual image. This one made me think of a three headed serpent. Thanks for looking.

Judging by what’s on the context toolbar you seem to be using the Paint Mixer Brush tool brush rather than the Paint Brush tool. Is that correct?
I tried to replicate what you did – including adding the Live Unsharp Mask filter as seen in the video but not the text – with both tools and didn’t get the same results but I’m not using the same original image or exact mouse gestures.

Are you sure?
As mentioned above they have different context toolbar.
 

All that may or may not be true, depending on (a) what shortcuts you have defined and (b) your preference choice for and (c) how many times you pressed B.
If that option is off, then pressing B multiple times will cycle through all the brushes that have B as their shortcut. By default that's the Paint Brush Tool, the Color Replacement Brush Tool, and the Pixel Tool. However, you could have changed that so that B applies only to the Paint Brush Tool, in which case pressing B a second time would take you to the previous tool you had selected, which could have been the Color Replacement Brush. Or you could have changed it so B applies to both the Paint Brush and the Color Replacement Brush.

Good evening, 
I continue to explore AD on with my iPad... 
I love this machine! 
Delicate subject, especially drops of water..... 
What do you think? 

@Jacobyte,
Are you dodging and burning destructively or non-destructive, by creating a pixel layer above your image and filling it with 50% Grey and changing the Blend Mode to Overlay. You then dodge and burn on this layer. Also by default the Dodge/Burn tools have a default Opacity of 25%. You might need to adjust it to suit your needs. 
Instead of using the Dodge/Burn tools, I just use the Paintbrush tool. Much faster. Make sure you have Black and White set for your colors. Then just use the keyboard shortcut X to swap between White (Dodging) and Black (Burning). Also pressing a numerical keys changes the Opacity, 0=100%, 1=10%, 2=20% and so on.  Learn the shortcut for increasing/decreasing your brush size and hardness. I can breeze through dodge/burn easily and quickly.
Dodging/Burning uses painting to lighten or darken, right? Well you need to be flexible, adjusting settings, brush sizes depending on the area your working on. You might even need to change brushes. Using a texture brush for say working on parts of an image that has a lot of texture in it. Most of the time I use an opacity setting of less than 20%, closer to 10% so I can slowly build up the amount.
I used to use PS, haven't for a while now. I also have Corel's PSP, and Coreldraw GS. I prefer Affinity Photo.

Nope. "Fill" relates to the amount of color. "Opacity" relates to how opaque that color is --- when dealing with the 8 special blend modes noted earlier..

Very Happy with this way of doing things - seems to be a solution. My thanks.
 

Salute together,
I'm new in the forum and new in the digital world. My English isn't perfect either, but I'll do my best.
Normally I paint realistically with acrylic, pencil or colour pencil. Because this is only a hobby, it was never relevant for me. But... but, I have a dream. To create a children's book and for that I have to paint digitally. Therefore, here is my start into the digital world. I take a Person I know, and it is the only Person (at the moment) I can draw in a "easy" way. Me. I work on that point.
The " little Äshi " will be my exercise object, so I will include new creations directly in the same thread and hope that's okay.
With the brushes of Frankentoon and Affinity Designer I created this colorful variation of the "little Äshi". As always, the sketch is painted analogously. This was the first expirience to draw with Affinity, an I like it! Start with the first digital Äshi!

 

The last train leaving the station. Demolition had already started.
Black and white photo added to modern Google Earth image then colored. Actually found a color photo of the engine, so I know these colors are right.

This is something I used to spend a lot of time with before my heart attack back  in 2015 and it's a subject that is dear to my heart. This effort was done between phone calls today, so it was a rush job and I'll likely rework it when I can get a decent sized set of images.
Some of the old architecture was so much more appealing than today's cookie cutter rubbish. Being born and raised in the New Orleans culture, there are lots of old structures that were removed to "modernize" the downtown area. by removing the old buildings that gave the city character and putting up some of the leggo looking structures that some folks see as an improvement.
This is a composite of an image from the turn of the 20th century (Southern Railway Station at the corner of Canal St & Basin Street, New Orleans, LA), an image from Google Earth (taken from about the same point on Canal Street as the old image). I combined the images using layers and masking, then I added some "colorization to the building matching what I was told the building looked like(I purposely did not colorize the people in the old pic). I personally did not get to see it because it was torn down and hauled away in 1958, less than a year after my birth it was no more. On a side note, Basin street was a one lane road designed for carriages with parking on one side, thus the street along the building has been narrowed accordingly.
Only posting it as it may inspire someone else to do similar work in order to remind people of what they've thrown away in the  name of progress, maybe even convincing some modern architects that buildings can be beautiful --- it just takes a bit more work than drawing different size boxes and connecting them. .
