• split themes into separate folder
• allow for switching between themes
• provide some preset themes (Default, Catppuccin, etc)

Preset theme sets may be feasible, custom theme sets seem more complex.

What do you mean by separate folder? A separate config file that only contains colors?

And I guess most importantly, do you even have nice color sets I could include? Because I don't know of any 😅

The default colors are made to approximate vanilla ones, yet the colors are gotten from Material Color Tool pallette instead of vanilla HUD icons.

a folder that contains the themes, and each theme is a separate json file

I have a config with catppuccin mocha but I don't think it's entirely polished

Got it.
I think direct resource pack support would be more beneficial than hardcoding some themes, so I've tracked that on #51.
No idea when or whether it will be done though.
