Is there a way to hide posts that have identical titles on identical sibling communities? My feed gets cluttered really fast when I'm subbed to a big community on two different instances because people often crosspost. I'm tempted to leave one, but I don't want to miss anything.
It would be very beneficial to have clients that support aggregating equivalent communities from multiple instances. When viewing a post from the aggregated community there could be a section at the top saying "Viewing comments from:" and then a dropdown to choose between "all instances", "lemmy.world", "lemmy.ml", etc. When viewing all comments, they would be in one combined feed, without the user needing to care about which underlying post holds the specific thread they're looking at.
Similarly, when users post something to an aggregate community, they could select whether it's posted to all the included communities, only one, or some specific subset.
