Self-made hotkeys. I play with a friend and I'd love to be able to bind /joinme [friend's name] in-game! This could also work for /respawn and other such commands.

The ability to sort our classes manually. I feel pretty lost if I don't sort by PR, but I'd love to put them in the order I prefer!

Per-page sorting for inventory. I know more than a few people that aren't very happy with the sorting feature, as it pulls from your last page to sort it into the first.

I hope the community has some more they can post, but those are the minor-ish changes that come to mind currently.

Edit: Just thought of auto-walking! I'd love to see that as well.
