Yes, Mark, I agree - the handling, as far as Ardour is concerned, is awkward and clumsy. The mix console itself is not really up to modern GUI standards either, but the sound does make up for that. I don't think I'll ever use Ardour for mixing, but I may end up doing stem/group exports from Cubase and then do a stem-based mix in Ardour, just for summing in MixBus. I actually did that once, and it does make a big difference.
I would never, never, never pay the regular price (219 US-$, I think) for such an incomplete product, as there are far better ones out there, but at 40$ you get a very decent sounding console emulation that's more than worth its price.
When I demoed the previous version, I hated it too and deleted it after a couple of days (at least it lasted that long - when I demoed Sonar twice, it did not survive longer than 10 minutes each time).
