I have added merge request with new "Reply on comment" feature. https://framagit.org/hubzilla/core/merge_requests/1614
Now you can enable button to reply on specific comment.
When pressed on you'll be redirected to comment input field where post author which you reply will be mentioned. Also "Submit" button will be marked with arrow indicator and floating hint.
This also should resove issue with Mastodon threaded comments https://framagit.org/hubzilla/core/issues/1357
