These are great. I have to say I prefer the less noisy alt-schemes, but these would be very nice in any capacity. Possible suggestion: (lightly) Color scheme them by their general areas, like green for civilian, Blue for military, yellow for diplomacy, etc. this would probably help new players a ton in understanding/remembering the functions of the buttons. Perhaps just a subtle color outline around the perimeter of the box?
If I were home I’d give it a shot myself, But I’m away from my computer for a few days.
