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.
