Determine if stack is maximized?

[Garrett Hylltun]

Rev 2.6.1

Greetings,

I found in the docs how to determine if a stack is minimized(iconic) by 
checking it's "mode" to see if it's "12", but saw nothing for 
determining if my stack is maximized.

Does anyone know how to find this out?

Thanks in advance,
-Garrett
