@CodeArtOnline This worked for me!
-Add the nw.js object to your layout
-Request "always on top" while in fullscreen.
What I have pictured is my fullscreen toggle (pressing ESC). I also have a fullscreen request during "on start of layout" on my very first layout. If you do the same, add the "always on top" request there as well.
Note: I had to click inside the window for it to recognize the keyboard. After that, worked great!
