Currently how I have my action bar set up is in a minimalistic keyboard, so its 2 sets of 4x5, the left-hand side is normal, the right hand is my shift, giving me 32 buttons that i can actively see.

What I enjoy having is my stances changing my main left-side, but because of how I have everything implemented, that only leaves me with 4 paging bars.

Technically since I have Bars 1-8 shrunk to only being 5 buttons, I'm not actively using 7 buttons on each bar, wasting a total of 56 actions.

If there was a way to offset buttons, instead of paging from bars, we could offset the bars?
So on my 12345 bar, instead of paging to Action Bar 11, I could just Offset Action Bar 1.
(1,2,3,4,5)6,7,8,9,10,11,12 ---> 1,2,3,4,5(6,7,8,9,10)11,12

Have you tried /dom numbuttons 20? That'll give you 8 bars with 20 buttons each. (Note that this will reset your action button appearance, so you might want to create a new profile before doing this).
