If using the disclosure triangles in this fashion is a workaround, how would you use them (for anything) that wasn't a workaround? This is something that has been in OmniFocus from the beginning, for this very purpose (showing only part of a collection). The iPad heeds the open/closed state of each group, too, so if you save a perspective you can have a complicated view restored with a single tap.

If you could easily do something like the Mac's cmd-click selection of multiple contexts, that might be better in some ways. My experience with multiple selection of objects in OmniGraffle for iPad doesn't cause me to wish for that, however. The disclosure triangles are easier targets to reliably manipulate, for me.

I think we are in agreement that it is often easier to determine that something could be better than to figure out how to make it so :-)
