Hello, I created this restyle for inkscape, if you like it you can get it on the gitlab page:
https://gitlab.com/sxwpb/ink-sx-ui
If you find issues you could report them on gitlab so I know about them.
Sounds good, but we’ll see how I do for the next major Inkscape release which goes from gtk3 to gtk4, i might have to re-write most of the theme
