How about a cli controlled window manager using Windows Presentation Foundation api capable of specifying all window layer hierarchy "instantly"? It is the only inhibitor to my software, Splinter. I have incorporated some "tricks" that allow Splinter to call more than just the bottom window layer in dwm but it has limitations. A WPF window manager is something that EVERY desktop interface level software "needs" before it can truly be unrestricted by the OS environment...
