Or if LsBox had more !bangs available for actions in a box (mouse in, mouse out, double click, middle click, click actions working inside of the drag rectangle, and setting more via !bangs), you could get most of it done with separate boxes and docking (and lots of scripting).
...if I could understand half the source from modules that I can actually get it for (grabbing the source--where does one do that for most modules?), I'd do some work myself. If I get some more free time soon (read: if I don't think finals will be too hard, as I need to raise my GPA badly) I might use LsWhiteBox and LsNothing as bases to figure out WTH is going on inside there.
