I have a really bad habit held over from The Place that Must Not be Named of subscribing to everything that looks interesting. If it isn’t actually active or interesting, it gets unsubscribed. Is there a way to sort my list here to see which communities are active?
There is no such a option as of right now. This also has more to do with the software itself (Lemmy) than lemmy.world. I suggest to visit their GitHub: https://github.com/LemmyNet/lemmy
Also, maybe some third-party developers can add this. In that case, you can ask the developer of your favourite app!
