Recently had some people tell me that connect isn't collapsing cross-posts so when a post is posted to multiple communities at the same time it floods the feed
The behaviour that occurs in lemmy-ui is it checks for posts with the same url in the ones its showing the user and removes any duplicates, only keeping the oldest one (and showing links to the rest in a cross-posted to section)
This helps especially in instances that recommend cross-posting since topics overlay between multiple communities
Should be relatively easy to implement since its just comparing the url values of the posts you already have
yeah ill probably have to make an issue on all of their repositories
its pretty much only supported by the main instance web frontends (lemmy-ui and pangora-ui) (been supported on lemmy-ui since before all of the apps were made)
currently recommended in programming.dev to cross post to as many communities as you can to give content to the lower activity communities and since there tends to be a lot of overlap with topics but thats conflicting with current app behaviours
