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
