It would seem like a good ideea to be able to bind asigning/Removing power to your systems to keys would be verry useful indeed... imagine this Pressing Q would add power to the shields whereas Shift+Q would substract.
The A-F row can handle weapons ... Z and X could teleport and beam-back troops..
That's my suggestion . It's mainly because i hate going all the way to the lower left to add power and activate my teleporter when all my clicking is done on the right side.
