Game Mode or Fullscreen Mode

my problem is, that I’m a gamer, when I’m in the fullscreen mode, it happends from time to time that I got thrown on the dektop cause of a new rule (which is “System” but if I allways block, the other trusted “system” rules doesn’t seem to work anymore, so I have to block them temporary). it’s a little bit annoying, to a button with game mode or fullscreeen mode would be very nice which supresses the rules popup, well and some settings for that like what to do if an app want’s to do anything.

thanks in advance

If you right-click the CIS system tray icon, you’ll see a game mode listed.

oh … ok hides I haven’t seen taht, thanks in advance ^^
