Nice stuff.
I didn't make a single wall until Kevin came out with the tall wall format. In my opinion, the default format (which of course is the same as FRUA) is a bit unweildly and space-wasting.
It was kind of hard to wrap my head around as a beginner.
Now, with the 'hyper' wall format, we are much closer to being "Unlimited".
Though, I guess to be truly maximized, each wall slot would be 176x211 so that you could use the whole viewport...
