PlayXpert is a game overlay that allows you to surf the internet, control music through winamp, chat with friends on IM’s, access google gadgets and mail, among other things all without alt tabbing out of a game !
PlayXpert is easily extendable with a database of widgets. There are widgets like, Gmail, RSS Reader, Armory checker and Notepad. Also has a widget for TeamSpeak, so now you know who is making whose funny noises on TS while you are raiding.
It supports XP and Vista 32 bit. 64 bit version of this software is still under development. Unfortunately on testing we found that the ingame overlay does not work on Vista (even 32 bit version), thus this is useful only if you are running XP.
