The new buttons for commenting and voting take up a whole bunch of space at the bottom of each comment. I think it would be more compact and readable if those buttons move up to the top of the comment.
The comment button could move right next to the three dot menu (or comment could become an option in the three dot menu).
The vote buttons could be combined with the vote counters already displayed (i.e. click the upvote arrow or upvote count to upvote the comment).
Even with disabling comment options I do think it would be a nice QoL change to allow hitting the number of votes to vote (ontop of leaving swiping how it is)
