I didn’t think it would be this nice, but it’s really helpful when browsing All to see quickly which similar-named communities I’m already subscribed to, and to block communities that I already know I’ll want to block without even seeing the sidebar.

I’d kind of like the ability to see which instance a community belongs to alongside the subscribe and block buttons. For example, there’s an instance full of interesting communities full of content, but it’s all posted by a bot based on content from Reddit. (I just blocked the bot account, but still.)
