If you can't help yourself to understand and learn the program, then DO NOT use it.. go to your Doku or whatever shit software you want to compare with construct.
Look how many beginners has learned much about the program by not being lazy of reading tutorials and stuff.
We're not going to spoonfeed you, the program won't give descriiptions to every word in the program.. It's completely up to you, and I think the community is not being unfair in giving help to those who really need it. What do you really expect?
EDIT:
What layers of complexity are you talking about???
the term variables and z-depth? research or ask to understand, if you're gonna complain cause you don't understand them, blame yourself.
