[FEATURE] dynamic window stacking

[b3nb5n]

Description of the requested feature

I have graph widget in a menu that is usually closed, ideally the graph would already be populated when the menu is opened. I tried using the :visibility property to just hide the menu, but if the window is in the fg layer then it will still consume all the mouse events in that area. if the :stacking property of defwindow could reference a variable or be set from the cli, the window could be completely hidden without dropping the graph data.

I would be happy to work on implementing this if someone would point me in the right direction
