And while we're on the subject :-)

It would be good to be able to control update rate from GRC, right now,
it just uses the
default.

Multiple-traces in "scope", and a "stripchart" mode would be good.
Actually without a multi-trace
strip-chart, I can't consider migrating my current apps to the Qt-GUI
side.

How are multiple "tabs" (Notebook) supported from GRC on the Qt-GUI side?
