Hey, thanks very much for making this! The plugin is working great with Krita! I've got a couple of issues though:
The NM Inspector UI is very small when I use HiDPI display scaling. It's not too much of a problem because the UI is quite simple so I can memorise what each option does. I'm using Fedora Linux 41 on a 13 inch laptop. I have my display scale set to 175%:

When I use other Godot programs, like the Godot editor or RPG in a box, they have a UI scale setting which lets me manually increase the scale of the UI.
