As scrolling to the bottom of the page to leave a comment can be a hassle on posts with lots of existing comments, an option to put the thread comment box above existing comments would be helpful.
If people are going to migrate to Kbin or Lemmy from Reddit, given the substantial downsides in doing so for the average Reddit user when comparing community user counts, minimizing differences — or at least giving users the option to do so themselves — might be helpful. While I wouldn’t rejoin Reddit even if there weren’t any alternatives, it would certainly be great if the alternatives had even a tenth the number of active communities Reddit still has.
To that effect, it would also helpful if there were a toggle to automatically upvote one’s own posts and comments.
If it’s really bugging you, you could put something like this in a GreaseMonkey script:
function move_comment_add() { let comment_add = document.getElementById("comment-add"); let comments = document.getElementById("comments"); comments.insertAdjacentElement("beforebegin", comment_add); } move_comment_add();
