I really miss the feature from Gnome2 and Mate that you can click on a panel app and the mouse cursor is hidden. The
mousetweaks package promises "... * An area to capture the mouse pointer until it is released with a pre-defined key combination." but the app is not shown anymore by default (xubuntu 13.10 - xfce 4.10). Is there a cool hack to get this back?
Edit: Imagine that sign in top RIGHT that looks like mouse is "The Trap" that when clicked catches the cursor (and releases when specific shortcut done):
