layout: Added sticky implementation for split windows

This continues implementing the sticky window functionality to
be able to keep a window, set as sticky, always displayed while
having the ability to activate/switch to other windows.

This could be useful in a handful of sitauations like keeping the nav
application on, while activing other windows.
