Consider providing a better mechanism for navigating up and down levels in a
workflow. Right now every time a composite actor is drilled down into a new
workflow window appears.  Having various “windows” listed in the Windows
menu could become way too cumbersome (we would have to put a scrollable list as
the list became large) so a better way to support navigation within a workflow
might be to offer some sort of cross between a hierarchical and “slide
sorter” view (e.g. the slide sorter in Powerpoint).  Each “slide” could
represent a level or view inside a composite actor so if three composite actors
at some level then three “slides” at the level.  Also make sure to
highlight in this view the current level the user is on.  We might need to
provide a list of all the workflows/files open in the Windows menu, with a way
to get to this extended "view" for navigating up and down a workflow.
