Feature request: a fun and easy way to link to the Sandbox room.
Currently (4:01 AM Tuesday, July 23, 2013 UTC), the chat formatting FAQ mentions the Sandbox room at the bottom.
I wish I could just do something like
[chat-sandbox] just like typing
[meta]. Might be also good to provide a link to the room on the pop-up that shows whenever I click on the help link.
