Sorry for the delay on this one.
We spent time on other Hook projects (1.2., 1.3, etc.). we also concluded in the summer that Tinderbox would require digging deeper into it, given that none of us was a user of the app at the time and the app is special.
I started a new thread related to what we expect to be upcoming support for it: Tinderbox and Hook - Discussion & Help - Hook Productivity Forum.
Cheers
