Multiple rows per hotbar

[Mhalak]

I want to set some hotbars as 4 buttons in 3 rows (or 6x2, etc.) instead of the current 12x1. I play with a gaming keypad whose keys are laid out like that, and I love it, but would like to be able to lay out my hotbars the same. Makes it easier to make the mental connection between "3rd button of 2nd row" and "3rd spell of 2nd row" than with "7th spell somewhere in the middle of one big row."

I'm pretty sure this isn't possible, but if I've missed something, please let me know. If not, is this being considered as an enhancement?
