I'm setting up edubuntu for my son's kindergarten, and I put shortcuts on the desktop for some of the applications. The problem is that when you double click an icon, you get no visual hint that anything at all has happened.
This causes even me to doubt whether my double-click was detected, and I end up launching several instances of the same application. I suspect it would be even worse for the teacher and kids.
Is there a way to get something to happen as soon as you double-click the icon? Alternatively, is there a way to put "Buttons" on the desktop, so that clicking them would create an obvious visual cue of being pressed and depressed?
