Hello LJDawson, let me start with saying how happy I am to have Sync back :)
The one issue I have with Lemmy is duplicated posts between different communities (see screenshot). Posts usually have same title, author and link, yet differ in community/server they are posted to. It would be great to be able to make the appear as one item on the feed with some note below that links to both instances’ posts, or something like that basically to make them not appear twice or thrice one under another.
It’s fine to dismiss the idea, because on reddit you could see the same user post the exact same article on a dozen relevant subs. If you try to hide them, which one do you hide?
It’s a stupid idea, akin to wanting to ban all reposts.
