Catppuccin OOTB support
Catppuccin should be the most popular Theme in the Coding community as far as I know, nevertheless its not coming with Zed out of the box. The Catppuccin Team is already working (maybe even finished) a Theme for Zed & I'm sure they're open to collaborate.
Not sure if you are aware, but you can install the catppuccin theme using the extensions panel (command palette -> zed: extensions). Repo: https://github.com/catppuccin/zed
If this issue is only about supporting catppuccin out of the box then don't mind my comment.
@bennetbo I know, I have the extension theme installed, but imo it would make sense to add it to the themes that come with Zed, since its so popular.
We're not looking to add any more built-in themes to Zed at the moment.
We may revisit in the future, but for now we're letting the state of themes evolve via the extension system.
