I hear ya, Easyscor, but I don't really have a key-press issue. I've got so many programmable buttons on my HOTAS I don't know what to do with them all...
I just find that the open radio box seems unnecessary clutter, if we could pin the 'radio roster' component alone. Used to stay pionned in the tower, even when the radio box was closed.
During squad ops, that list helps us get and stay organized. Nice when you can keep it visible.
