Yep. The Q44's also short-turn at Whitestone-14th Avenue (deadheads back to depot after), Lafayette Ave (first stop in Bronx) and H. Grant Cir (last 2 are unofficial layover IIRC).
The original plan for the Q94 was Flushing-Fordham Plz, dubbed a "super LTD", dunno what that means or how it works but I think it would be hard to find another way to Whitestone Br without replicating the Q44 too much or going too far out like College Pt Blvd and then the ridership base is another problem to tackle as well. Not many people transfer over......well, actually, a decent number do transfer over to the Bx9 after the 44 but that might just be terrible timing with the Bx9 which manages to find itself bunching one way or another.
