Hi Bill.
I think separating the the scan from locating packages containing
missing drivers is an excellent idea. Finding missing drivers should be
close to instantaneous (based on prtconf -D which does this and runs
quickly.)
What would be in the second window? If both windows would have a lot of
the same information, I would prefer to see a single window, populated
in phases, first by the scan and then by the search for missing
drivers. Two windows to me would seem cluttered.
Thanks,
Jack
