My review after like 5 min of testing:

It has the basic things imemented and they seem to work. At least I couldn't break them with basic usage. The performance has a weird bug. The proformance gets progressivly worse the more projects I open. But only the new projects have terrible performance. The first one still works normal.

It has only the most basic features implemented. Like things you could do on Krita as well, only that Krita can do more.

The ui has some oddities: on the top left there is a button with the current tool you are using and a chevron (idk what it is called) indicating a dropdown. Both do nothing. Or at least I couldn't figure out what they do or when they become active.

If you disable the ui elements on the right side it will still show their toolbar. The toolbar also remains active. This is a bug as switching modes removes them. if you enable and disable one then it is there again.

I cant rightclick on the empty space in the layers tab. Idk if that is a feature in PS, but I instinctively did it so there is some muscle memory there.

tldr: I kinda works. Very basic tho.

The settings are just as hidden here as they are in PS. So good job on that one?
