RE: The menu delay, I've been meaning to fiddle with that setting +Ashish Bhurtel
mentions. But serious question: Why would you ever set any delay at all?
At 0 it still feels almost no different, turning of transparency seems to have little difference. tbh the menu is good overall, combined with Gnome Do I have a really workable solution.
The other nice thing about using Gnome Do, is I can use it on just about all the other desktops too. So it makes for a steady workflow.
