Just saw this thread after replying in another topic.  This is even more relevant than where I replied.
While familiar with Affinity Photo for DSLR photos, I'm now just dipping my toes in the water for 360° photography.  The output of my 360° camera's stitching software is a "raw" DNG that preserves the full dynamic range of the two sensors' data (and for HDR images, I have the option to export multiple DNGs for an HDR Merge).  Naturally this opens in the Develop persona.
The Develop persona (just asked for a 360° "preview" option there) works perfectly with some adjustments: Exposure, Enhance, White Balance—I think even Curves does its job—without creating a seam at the edges.  But if I play with Shadows/Highlights or Tone, I can end up with a gnarly seam.  Same with HDR Merge.  If I wait on adjusting tone or shadows/highlights until after development, I lose all that beautiful latitude from the raw image.
I don't know of a way to duplicate/wrap around the edges of a raw DNG file and still have it be a DNG.  Layer live projection is only available in the Photo persona.  Has anyone found a better solution?

Thanks, @kirkt.  I will use the Feature Requests forum.
Appreciate your advice on caution with adjustments.  The raw 360° photos I have developed in Affinity Photo look surprisingly good for what seems like a toy camera (no issues with mismatches along the "seamless" edges).  But that 360° preview capability in Develop would make life easier from a decision-making perspective.  Because the live projection is layer-based, there are some special considerations with adjustment layers, but that's later in the workflow anyway.
Yes, the stitching software is very basic for raw photos: take in an unstitched DNG, check the stitching and horizon, spit out a stitched DNG or stitched DNG+JPEG (no color adjustment, no offset/shifting/recentering of image content).  After it spits out the stitched DNG, that software has no more role in the workflow—it's all in the hands of other photo software to grade/develop the DNG and do other adjustments.  Although there's no "feedback loop" for this particular stitching software, your Smart Objects idea would be useful in so many other applications.  Keep up the crusade!

Hey there!
Lastly when I was retouching a bunch of photos, I have used LUT's as part of my workflow. Found out that certain LUT's work superbly on "Average" blend mode. But that's not a core of the suggestion I've come with during this process.
I have a really big collection of LUT's, currently I use a LUT preview small photos I did on some example and based on that I try to select the one I would like to use in AP. But it's not really comfortable, and here comes the core of my request - to add some kind of gallery or organizer, that let you showcase the end result of LUT applied with a selected blend mode, and it doesn't crash such as preset tab when you have a ton of them there. It can be just a separate window, maybe even something similar to "filter gallery" in Photoshop. Or you can use simply a dropdown that you can scroll with your mouse roll and see the effect applied. Of course the separate window is the preferred option, but just an alternative that works is okay too.
So to summarize, a simple TLDR: The request is for a simple organizer or gallery of LUTs working with ton of them. I don't exactly recall when the preset window started to hang the app for a long time or even crashing it, but it is not working with a large amount of LUTs. 2 options suggested:
1. Another window opening with a gallery with preview when you put a LUT adjustement layer
2. A dropdown scrollable with your mouse roll in the LUT adjustement layer's window
 
Thanks for your superb software so far, keep it going Serif!

Hi
I'd like a feature to preview several LUTs against an image quickly or flick through all the LUTs in a folder to see which works best. Going in and out to try different LUTs is too slow.
Thanks
