[Cuis-dev] ThemeCustomizer: Save and Manage Personalized Themes

[Juan Vuletich]

I fully agree and support what you say.

A first step would be to do #experimentsTowardsANewColorPalette in 
OkLCH. Next step would be a Morphic color picker based on that. Anyone 
wanting some color fun should try to build this!

Cheers,
