First at all, congratulations for your great work!
I'd sugest the creation of a step-by-step guide in order to show new users how to quickly create a simple workflow application. This way you'll get users, feedback and technical sugestions, contributing to build an even better application framework.
The way it is available now, you'll only get feedback from developers and Notes fanatics. A great application needs to be closer to the real world, the real users, and this includes not so experienced programmers and technicians.
After the "hello world" workflow, there will be always a lot of questions like "how can I do…", contributing to a very useful FAQ.
That's my $0.02 by now…
