I'm not saying that he should keep pumping out new features for ST2 - it's totally fair to draw a line under it on the day it leaves beta and say "no more features". My complaint is that he took ST2 out of beta while people were still complaining about bugs, and has subsequently only issued one bugfix release.

As both a user and a developer, I don't think it's unreasonable to expect paid software to get support and bugfixes for a while - at least until the next version leaves beta. "Pay an extra 50% and maybe I'll fix the bugs" doesn't seem fair.
