Feature Request - Option to hide windows with timeout

[Rogermilne]

I like how the menu access window fades out after a few moments, and can be re-summoned easily with a click.

Any chance an additional widget could be added to the top of all windows (beside the move/resize/zoom/etc) that is something like a "timeout". I.e. when enabled, that window would also observe the same hide/show state and fade-in/fade-out of the menu-access window.

I think it would help declutter the cockpit in some situations, such as periodically referencing a map or document, or occasionally using the Superbug's UFCD (which only seems to work through a window?)
