Thank you homers, fubhy and contributors for this wonderful theme.
How about breaking all zone into 3 regions? I believe this would be more versatile.
I think this simplify template generation because all one has to do is specify n rows X 3 regions.
p/s - for those whom are not familiar with this theme: Omega can have dynamic region, when it's empty, the adjacent region can expand to fill up the empty region.
