It’s a great feature while browsing All/Subscribed/Local, but some people (including me) seem to think this can be confusing/annoying while browsing a specific community directly.
https://github.com/LemmyNet/lemmy-ui/issues/2104
Any thoughts on this?
Make it a client side option
It is. Different clients handle it differently. If you note, the repository where the request is made is for lemmy-ui, not lemmy backend.
E.g. Photon shows a single item with a dropdown to expand matching posts if they were posted at the same, which is common with cross-posts on All, Local, Subscribed feeds.
And then it lists all cross-posts on individual pages in a neat list with stats like votes, number of comments, etc.
