There are many goodies here, including an HTML section (the area marked "Connecting to Profile Server"), an area for making notes about a player (which are also displayed at other times, such as when you receive an invite), and the ability to mark a player as a friend or to gag them.
Also, BBGT keeps statistics on all your matches. You can view your match
records against a player in particular or overall. Records are broken down
by matchlength, and the result of the last match is noted.
