Last I heard they had one more bug two work out, they might be taking a bit of a break, before finishing it. From the screenshots it looks like a lot work... which would be understandable.
I've put the linking sections of my own site on hold till they release this. So I'd love to be able to use it as much as everyone else. But I'd like to only have to install it once, if that means waiting a bit longer for a stable script it's all good
I think he said something about a new job as well... that always takes awake from hobbie/design projects...
