That's awesome to see! π I actually found one or two of your repositories back when I was looking around at how people were using Palette (to not develop it in too much of a vacuum). I'm happy that you're finding it useful! Do you remember if there was any specific feature, when picking the crate, that you found particularly nice or helpful?
Also, don't hesitate to let me know if anything is missing or can be improved for your needs. π I try to keep the scope somewhat focused, but I'm always open to ideas and feedback.
I haven't used it personally, but our UX lead is designing the theming system, whereas Ashley is working on theme support for libcosmic, and they were looking for something that supports oklch to generate themes from selected accent colors.
