Comment 12 for bug 1182734

C'mon designers, haven't you read your Fitt's law? Edge-swiping on a fullscreen mobile app is great, because the "edge" target is effectively infinite in size, so it's an easy swipe. Swiping up on a windowed desktop application is infuriatingly impossible, because the 1px target is *tiny*.

Yes, obviously there are a range of devices and the concept of "desktop" is nebulous at best, but it should not be difficult to come up with a reasonable set of heuristics for when it makes sense to lock the toolbar open. Something like "Only autohide the toolbar when the app is running fullscreen and there is no mouse connected"

As far as I'm concerned, the presence of touch input is irrelevant; connecting a mouse should lock open the toolbars. But even without a mouse, Fitt's law clearly indicates that a hidden toolbar that is not at the extreme edge of the display is a bad idea.
