How to keep AWN up but below all windows always?

HELLO ALL! AWN 0.4.0, looking good, nice improvements. I was hoping AWN would pick up an "always visible but always below" behavior option, it's what kept me from using the program in the past on the netbook. Every pixel counts vertically, so much so, that when browsing for example even those bottom few pixels need to be kept open and free from triggering any sort of action. Hopefully I am overlooking a config option on this one. Also, with reference to other behavior options, what precisely is "window dodge"? What makes "intellihide" different from a simple autohide. What does "custom" do? Any help is appreciated. Thanks!
