Features

- Masthead is hidden until the mouse reaches a trigger distance from the top edge
- Adjustable trigger distance (in pixels)
- Adjustable hide delay and animation speed
- The masthead stays open while you hover it, type in the search field, or use its menus
- Keyboard friendly: pressing "/" focuses the search and reveals the bar
- Does nothing in normal mode or real fullscreen
