Comment 197 for bug 308191

Is there a way to configure a zone other than RTCornerButton, RBCornerButton, LTCornerButton, and LBCornerButton?

As in, can I set it up like so:
-------------------------------------------
| button 4 | | button 5 | LTCornerButton = button 4
|-------------+------------+-------------| RTCornerButton = button 5
| |
| |
| |
| |
|-------------+------------+-------------| LBCornerButton = button 1 (Left Mouse)
| button1 | button 3 | button 2 | Rb CornerButton = button 2 (Right Mouse)
------------------------------------------- MBEdgeButton(?) = button 3 (Middle Mouse)

If not, I would like to request this feature.

Also, how do I make the CornerButton areas larger? Is that the LeftEdge, etc. values?
