Note also, for whom it matters: A single crossbar set (controller) is 16 buttons. Two sets is 32 (can rapidly swap by tapping the right bumper). Conversely, for keyboard and mouse, grids are in sets of 10s (10/20/30/40).

For keyboard, the grids are in sets of 12, so three hotbars for a total of 36 slots covers almost every job by your methodology.
