We're still working on FoldingText :)! However, a lot of that has been behind the scenes as we're working on a new version from the ground up. We're hoping to start private beta in a couple of months.
It will be a paid upgrade. I'm sure we can work out how to migrate our customers who have bought FoldingText recently, but, honestly, we still have to figure out these aspects. Right now, we're heads-down on getting the beta out :).
Also, while FT is in beta it will have a significant discount.
