Ha, thanks (I work on it). Both for the comment and for upgrading to pro. There's still like a bajillion things we can do to improve it. A few big features, but a bajillion smaller usability improvements that add up to a really big deal.
My first development job was on MORE, shortly after Dave Winer sold it to Symantec, and your product comes as close as anything I've seen to the feel of that product. As I'm sure you know, it had a fanatical following.
Even though I probably won't be able to use it for my day job, I'll buy a license and toast your future development!
