> AM has five or six inner classes, it takes zk callbacks, it has distinct Maps
> that are supposed to be edited together (regions and servers) and that then
> have some interaction w/ notion of regionsInTransition, etc. It could do w/
> a tune-up so it comes back into the realm of the penetrable (currently I'd
> not be surprised if its workings were beyond the ken of all who here code).
