Yea, Materialious is a bit more complex then a theme as it has a lot of custom client side logic (Like sync parties, playlists, etc).

If I expanded Materialious you’d still be able to use just Invidious or Safetwitch etc.

But Materialious at its core would still be built of the API of giants. So it wouldn’t be reinventing the wheel for scrapping/handling data from twitch, YouTube extra.

Haven’t used Proxitok in a while, so not sure if its working currently. Seems to be in active development tho.
