1. Developers shouldn’t do app that can fit one person needs. You can easily add textures you want to background. You can make template file with textures, duplicate when you need to work on new file. It’s really not a problem.
2. I’m totally fine that selection is still on after transform tool is done. It’s absolutely normal behavior. If you compare selections in Procreate and ASP, I’d say that Procreate had and still has terrible selection tools. That’s the main reason why I moved to ASP year and half ago. Procreate works much more fluent that ASP, but ASP is more functional and convenient.
