I believe we are all very synchronized on this point. The thing missing from the
current framework is the actual feedback bit. We've got the latency under
control, we've got the notion of gesture primitives that allow us to detect
rotation before we commit to it being rotation. What we need is the UI part that
allows us to see something happening.
