Not see the same post over and over when scrolling down through "Home", "Federated" or "Explore" timelines

Once is enough. Seeing the exact same post repeated while scrolling down seems wildly unnecessary.

Aside, I really like the way elk doesn't lose scrolling position after diverting back from a thread (it does occasionally, and goes back to the start, but reloading gets it to remember again).

I haven't found a place in Mastodon to post suggestions, but I'd also like to see posts that repeat the same image or URL be tracked together... i.e. a counter of repeats shown, and like a post, clicking on that goes to all the repeated posts. The client would have to make an MD5 sum and submit that to a database where every federated server would have a binary search of that sum (ditto for normalized URL). It would also be nice when posting to have the server query the user "do you know that's been posted N times?" and allow the user to go to where it's been posted and add to that post rather than starting a new one.

Something like the old usenet style of categorization would be nice too. I know hashtags are supposed to do the same, but needs major categorization too.
