I'd have the following not closely related ideas:
1. During the missions the selection cursor (brick?) is sometimes hard to see (depending on lighting settings and environment). Either a setting for color/thickness would be nice and/or the lighting should not be applied to it (display always with actual RGB).
2. When equipping the squad, the 1-8 key selection would be nice and probably easy to implement. Also the up/down (mouse wheel?) could select the next/prev one. This latter would also be very helpful when hiring soldiers (to find one with specific abilities)
3. I equip the soldiers with weapons that's appropriate to their abilities. Though the order is quite random like assult/sniper/bolter/bolter/sniper/etc... It would be nice if the order of the soldiers within the squad could be changed.
4. A list of well documented commands suitable for bind* would be greatly appreciated
Also, as much commands for keyboard binding as possible. I especially miss the shortcut for the new reserve time for kneeing feature (or I just don't know it?).
