I miss multireddits, a workaround I found is to create accounts on different instances and subscribe to different communities with each account ie
News trabic@lemmy.world
Memes and other bullshit trabic@lemmy.one
“Math” trabic@lemmynsfw.com
Then just login to which ever one I’m looking to browse. I don’t think this will screw with the fabric of the fediverse, is there any reason I shouldn’t?
I know it is not the main topic of discussion but, there is a discussion on Github about multi communities for lemmy, if you have a GitHub account please upvote it, or you could add a bounty to it.
