The hotkey mode without mouse interaction does what I need. But a minus is that the mouse cursor is also hidden.
"Mouse Interaction - Show when mouse is over control" is what I really wanted (like MPC-HC in full screen). But when I move my mouse to another monitor the video controls reappear (which I don't want).

Currently, the addon does nothing by default since the default settings have both mouse interaction and hotkey disabled. After you install the addon, you have to manually enable mouse interaction in the options for it to work as expected, which is certainly unintuitive. Once enabled, however, it works brilliantly.

Great addon, could be improved by adding the option to hide the controls on the right border

Great for quickly hiding the controls. Would give it 5 but I'd prefer to use the right side of the screen. Perhaps this could be a future update.
