Let me put it this way:
layers = best way to drive the user up the wall = evil
(same is valid for window that raise or maximize themselves - or
worse: both)

Transients should give reasonable results. Lets assume B and C
are opened from A, D is openend from B and E is openend from C.
The set the transientfor property of the window to
window transientfor
A -
B A
C A
D B
E C
