I hate to be the one to bump but since I still don't have the skills nor tools to modify the source I'd ask would it be possible to modify the tasker so, that it'd take the 80 % of the screen when one item is visible, 40 % (or so) when two to four are visible and after that it'd take the normal space? Check the first post to understand the method, it'd be sort of a hybrid between normal, two and one-panel tasking.

For now, that'd be the best multi-tasking for me.
