Three-mode full screen that always lets you step back

One button cycles normal, header hidden, and full browser screen. It lives on the timeline so it never disappears.

• Mode 1: top menu and toolbar hidden
• Mode 2: browser full screen as well
• Works with F11 too
• Logo stays visible in every mode

Chart first, controls where you need them

Cycle through the modes with the corner button. The timeline, positions bar and the button itself stay on screen, so you can always return to the normal layout.
