While seeing more work on server stability is definitely nice, I would much rather we have the option to just host our own servers so we don't have to take up your resources and so streamers don't have to worry about accidentally leaking a code. I know this was in essence planned for the game's post-mortem, which is of course very appreciated, I'd rather have it sooner than later.
Also, just to add to the pile of suggestions here in the comments, please let us impostors move through vents using WASD ;)
