Hey hello,

Of course, simply add it to the end after the crew messenger.

[Window Titles]
Window00=Main
.
.
Window10=Crew Messenger
Window11=Com2


//--------------------------------------------------------
[Window11]
BACKGROUND_COLOR=2,2,2
size_mm=250,556
position=8
.
.
.

As is I said, the Hotkeys are only working to Window08, all other 2D Panels above you have to activate via menu.

A possible solution would be if you move the Standard Radio Stack to the end (Window11) and the default Com to Window04. Nothing would be overwritten with this step  :)
