We also have a new way to switch between chatrooms: Just press Left or Right while the textbox is empty. If you're on the downloadable client, Ctrl+Tab and Ctrl+Shift+Tab also work.
And if you type someone's name in chat, it'll give them a notification and highlight the message (you can turn this off in the Options menu as usual).
Also, I recently fixed faint order order (with some help from V4): now, if your last two Pokémon both faint on the last turn, instead of being a tie, the Pokémon that faints last wins.
