It would make my life easier if we could do bugfixes when they were available. Weekly for that. As far as new plugins maybe every other month at least. I work every day in my studio and have some very tight deadlines staring me in the face and then here comes an update that ties my computer to get a new toy and then figure out how to use the new toy if it is something I can use. That time taken away, even if just 10 to 15 minutes, eats in to my work schedule something fierce sometimes.
Bugfixes to me are far more important and justify updating on a regular basis. That update is worth it if it helps my rig run faster and more stable!
Anyway, I think about those guys that are in development sitting in a cubicle sweating because they have got to come up with some new earth-shaking plugins every month. How long can they keep that pace up without getting burned out? My hats off to those guys! Lighten their load a little and do the plugins every 2 to 4 months. Get them on the bugfix. Love you, guys.
