Looks good. I’ve always found it annoying that lemmy doesn’t do this by default.

I’m not sure about the license though. Creative Commons recommends against using their licenses for software, since it doesn’t include terms regarding source code, doesn’t handle patents, and it’s usually incompatible with free software licenses.

The biggest thing is probably non-destructive editing, so you can do stuff like apply filters without them changing the underlying image. Gtk3 should add better support for tablets and wayland. There’s also better layer tools and font support. A lot of it was on the backend, which should eventually allow for using other color spaces like cmyk natively.

It’s too bad that GLIMPSE fork never took off.

They’ve been working on porting it since back in 2012, and didn’t want to redo a bunch of the porting work before they even released it.
