Tooltips does not exists in QuickGUI?
Tooltips don't exist. It would be a good feature to add, but its one of those more mature and non-fundamental features. Maybe with later versions this can be added in.
I think this is veri important future becouse all normal games contains help for all GUI items.
Really? I would think if your game needs tool tips for its buttons, then the GUI is too complex. Let me think about how to implement this.. right now the big task is getting double click to work correctly. Maybe I'm out of the loop on games, but I don't remember seeing tooltips over menu items. (I tend to think of Wii games, simple and to the point. But I shouldn't enforce my GUI philosophy on others..
