When the folders were first introduced I requested this and I've yet to see it implemented.
I'd like to see folder names take the following form in the sidebar:
Folder Name (x/y)
x = the number of games where it is your move
y = the number of games in total in the folder
For those entered in tournaments, siege games, and clan games we cannot be sure when a game is going to pop into our inbox. This becomes a problem if you have set your folders up so well that you hardly look in your inbox anymore.
Adopting the above method would cause people to look in their folders less as they will immediately see if there is not a game waiting in a certain folder, thereby it will reduce demands on the redhotpawn servers.
