...It can, install steam games, uninstall, play, validate steam game cache files, defrag gcf, restart steam client, set your steam status online, away, busy or offline, but that's not all, you can set isteam custom background image, check for latest version of isteam(but not download it..) and ofcourse it has a little command, a button that's say 'Activate', once you hit it, it will start spamming your steam status, this can cause a following, ignored by all your friends, removed from group, etc. So, gentlemenes iSteam is begin cool and fun. Give it a try, you should like it. And ofcourse, last feature of that little application can do, once you play games thru it, it will get you 2-5fps in-game performance & much more. MAKE YOUR STEAM ACCOUNT BETTER.
(I said this just like ..)
Have Fun!
