Yeah I was also thinking about multiple users for this, but that’s a terrible hack on so many levels…

Yeah that sounds good too, but it’s not the same thing. I just want a client side filter for lists of communities. No need to involve AP or get consensus amongst many users/communities, just my preferences. If we want to get fancy, have some APIs to store these lists server side so or can with across clients - still strictly single user. It feels so simple I am tenors to get my hands dirty, but for one diving into a new project is usually quite since work and it hardly ever turns out to be as easy as it seems (then again the new python lemmylike thing already has it instance wide, so it at least is doable).
