Are there any plans to allow us the ability to set how any given actionbar is drawn?

direction & order.
  • left-to-right, top-to-bottom
  • left-to-right, bottom-to-top
  • right-to-left, top-to-bottom
  • right-to-left, bottom-to-top
  • top-to-bottom, left-to-right
  • top-to-bottom, right-to-left
  • bottom-to-top, left-to-right
  • bottom-to-top, right-to-left

In addition, be able to set the number of rows and columns:
  • 1x12
  • 2x6
  • 3x4
  • 4x3
  • 6x2
  • 12x1

For example, it takes 3-4 action bars to make a layout that may seem intuitive for a Logitech G600.

Controlling how action bars are drawn, you could to cut that down to just two bars.

I won't go as far as controlling the amount of empty/white space in between a given row/column/slot. Perhaps that is in the realm of the add-on api, whenever that gets released.
