Looks great!

Would you consider adding my Lemmy theme as well? https://github.com/pkrasicki/lemmy-modern-ui-theme-addon

It seems that they need a UI expert.

Yes, finally!

On desktop I recommend FreeTube app which uses Invidious https://freetubeapp.io

Perhaps you can read about Mastodon and how it works. It’s also federated, but much more popular, so it might be easier to find information about it.

The front-end repository is actually: https://github.com/LemmyNet/lemmy-ui

Edit: I suggested some changes to the default theme. Here is the link if anyone wants to take a look: https://github.com/LemmyNet/lemmy-ui/issues/1183
