I realise Affinity Photo doesn't allow animated GIF editing currently (only the first frame is loaded), and i read in the help forum it isn't planned. However, I would love it if:
1) When an animated gif is loaded, each frame is loaded into a timeline, where you can set the time delay for each frame.
2) Each frame is on its own layer for editing
3) The edited gif could then be exported as an animated gif.
It is one of the only major features I miss from Photoshop, and yep, I am aware you try to avoid direct comparisons, and I understand why.
So far, the program is great though! Thanks.
