I think some AI upscale, AI bg remover, AI bg generators in Photopaint should appear very soon.
Up sampling of images using an AI feature has been built into the resample command for 3 or 4 versions now.
If Corel needs to improve image handling remove the 30,000 pixel limit.
Background removers and generators wouldn't hurt but that's Affinity and Photo-PAINT stuff.
A decent chromatic aberration remover would be great as would be in additional to the already existing filters a blurr removal filter.
