I'm glad you like it so far!

1. In the section explaining the command structure:

Exceptions:
   Adapted boxes: x is a (for adapted) y is the position of the box.

I noticed that you x and y values can be swapped around i.e CBlabox seems equivalent to CBalbox

I used CBalbox, CBacbox and CBarbox when I wrote the plugin at first, but for consistency in the nomenclature, those are deprecated in favor of CBlabox, CBcabox and CBrabox. And you're right, the explanation in the doc is not clear, I changed it a bit, I will replace the image for clarity later today.

2. In the Commands->Boxes section, the second to last entry in the table CBbaox[num] is incorrect. It should be CBacbox[num].

Fixed, thank you!
