Visibility Zones

This is how it works today - endless (not well thought) up-down mouse jumping. I think we can get rid of the extra tab Track. We can manage both functions in one window - Zones. Visibility with a simple mouse click and Zone management with Ctrl (or Alt)+Click. Or at least put all tabs at the top of the window not at the bottom of the screen (very bad idea).

Putting Tabs at the bottom of the window is counterproductive and counterintuitive.
