One feature I’ve not seen anyone implement yet and I would love to see Windows 7 implement is the ability, in presentation mode, to disable all (but the critical) system tray notifications, this includes software pop-ups, IM’s and notifications.
Back in the consulting days I always had to remember to kill all the system tray apps that might pop something up before starting that major preso. Since Windows now goes to the effort of offering to present your desk top in presentation mode, it would be nice if it would automatically supress these kinds of notifications.
*sigh* i need to get me a copy of this bad boy.
