Dont know if this was already suggested,but my suggestion is a command to save rooms,like /hl add. People who use multiple rooms(more than 10) have a hard time joining all their rooms of interest w/ the /j command. So making a roomlist like "/roomlist,trivia,thp,ct,help" first and then typing "/j roomlistone" to join all rooms that were saved will be a very useful and more comfortable method to make PS! usage more easy. It might be a small but very handy addition to Showdown!.
