1. Have it show 3 levels instead of only one at a time.
2. Number the columns 1 2 3 4 5 6 7 8 9 0.
1. There are just too many things to have up there and 10 spaces are just not enough to have immediate access at any point in time. Between nanos.. macros.. health/nano stims/kits speed stims I feel it necessary. I have a hard enough time twisting my fingers around to hit shift/# while running around a mission.
Have only the first row affected with the number you hit but show 3 lines. The other 2 lines should be available to click.
2. It just makes sense to show the numbers at the top of the bar across the screen.
