Hej Affinity,
when using the In-painting brush in Affinity Photo on iPad (6th gen), it always takes some time before it has done the calculations and the screen turning into a loading screeen meanwhile.
This is ok, it's not terribly interrupting, but having these operations happen asynchronously would be nice.
However sometimes I accidentally mark areas for inpainting, mostly when using the Pencil and use fingers in between to zoom or move and in those cases I wish there would be a cancel button.
Thank you for maybe considering my suggestion and have a great day and weekend!
All the best,
Sebastian
Ps.: I love Affinity Photo & Designer on macOS and i(Pad)OS, they make me wanting to do more graphics and photo editing. Its hard to resist getting Publisher as well.
