I too would love a single staff, but for me it seems like it would be most useful if it were a "shape" that I could extend to whatever length I need.  No need for clefs, etc.. I would just write in that sort of information, plus, if you're just adding alternate lines, or arrangement ideas to a lead sheet or existing part, the clef, key, and time signature are implied.  Right now I make 5 lines with the shape tool, but it is a little cumbersome and hard to make them even and straight.

A single blank staff with no clef, time or key signature, measure lines, etc would be perfect for my use! I often want to add notes or a line from other trumpet parts where I need to cover for them or just add bits from a D.S or coda when there's a wacky page turn.
