Hey, all:
I was searching for what I assumed would be named 'classification system' or 'organizational outline' in order to understand the arrangement of Appropedia's information. Call me 'thick-headed' but "All categories" doesn't express the idea very well. I suggest one of the names I had assumed it was, or other expression. "All categories" does not imply classification or outline, but a simple list.
In any case, I now can see better how things are organized.
