This feature was one of the most convenient things I’ve ever experienced in any app ever. It’s one of the reasons that Apollo was so endearing to me and others I’m sure. And I’ve never seen any other app that does it. If there is any way this could be implemented it would elevate Memmy above all others.
Ivory for Mastodon also has it, and I'm assuming it came from their Twitter client (never used it myself though)
