Glad you appreciate the input. Dont want to overload you but there are a some more things i could suggest from the perspective as a user.
User experience:
1. Some visual feedback when you save via ctrl+s/menu
2. The select tool could give some kind of visual indication when you have copied something
Currently it feels sort of ambigious when you do these things. I find my self preferring to use save via menu because then im sure I have saved.
Qol and workflow:
3. Shortcuts for creating, deleting and renaming layers
4. Layer duplication
5. A text tool for writing
6. It would be handy if the rectangle tool used corners and horizontal/vertical lines when a line glyph is selected.
Such a great piece of software, been having a blast with it. Thanks again!
