Hey! thanks for the PR :)

Looks really good, thank you! I have two thoughts to run past you:

• do we need to add all 5 themes? can we just pick the best / most popular one?
• can we use a shorter name/id? the dropdown looks a bit weird with the super long name!

let me know what you think :)

Hey @lucko, sorry for the late reply, I completely forgot about this PR.

• do we need to add all 5 themes? can we just pick the best / most popular one?

The OLED theme can be omitted as it's not an official palette and just a small community tweak that I thought would be nice to include. As for the 4 others, they are a big part of the brand and mostly ported together so I don't think keeping just one would work.

• can we use a shorter name/id? the dropdown looks a bit weird with the super long name!

Maybe some kind of secondary dropdown system that would hide the 4 palettes until you hovered over "catppuccin"?

Sounds good to me
