I think Bohemia should remove the squad commanding hotkeys, which are ',1,2,3,4,5,6,7,8,9,0, and give them a single key with an improved interface.
If that were to be acomplished, it would also give them the possibility of using 1,2,3,4,5,6,7,8,9,0 as weapon selection keys.
' (or ~, depending on your keyboard.) - Squad commanding UI.
1 - Main weapon
2 - Secondary weapon
3 - Launcher
4 - Binoculars
5 - Grenade type
6~0 - Extra keys for future use.
F1 ~ F12 Still should be used for selecting units.
