There should be an is-visible option for menus which you can edit on and off. Sometimes you might not want to see that stupid menu bar on the top of your screen. I think it's ugly, personally.
Speaking of ugly menus, maybe a way to customize the look of menus? Uploading a picture for it, changing the text, etc?
If we got some kind of onMouseEnter/Exit properties for interface controls (buttons, primarily) you could make your own menu using client-side winset commands.
