Wouldn't it be great to have a top post with the list of suggested things and the voting mechanism to figure out popularity? Better transform, paint mask and selection edge refine tools would be my top choices. Vectors would be great, but it's much bigger deal to add. With all those (and the plugins Dev tools), ASP can take on PS and Affinity Photo. The strongest part is that it's the only professional app today that works equally well on desktop and mobile. Well, considering the limits of the mobile of course...
