- Larger upvote (and downvote) buttons.

- A way to format lists without adding blank lines.

- On mobile (Android), the comment box lacks the attribute that allows word completion, etc.

I could consider upvote-capping: not in absolute terms, but maybe at 110% of the next most upvoted peer at the top-comment position.This would allow for more top-comment dynamics which currently is often runaway.
