What we’re really lacking on the ui end is a way to see groups of identical communities that are on different federated platforms. Hence the idea of a dom-lemmy. The way it would work is lets say you search for a cat community called “cats”, there’s at least dozens of them out there already. Instead it would return the cats dom-lemmy, with the option to either drill down to a specific instance, or to merge all sub-lemmys called cats into a single view
I like it, but I also can see some issues with it where communities grouped together may have different rules and standards for posts or comments. Even on kbin it’s hard to see what instance a user or thread is coming from so keeping track of multiple rule sets across domains could be tricky.
