It's honestly too many years ago now to remember, I just remember trying a couple of perfectly reasonable things (maybe attributes, maybe multiple sub lists, I'm not sure) and having it break. But I think it only broke when you created a new template, not when you were using an existing one with new data, or something along those lines. You could make a change and not realize it broke things for a week.

It was incredibly temperamental too. I got the initial bare bones demo working and showed the powers that be, but after that a spent a week trying to do it again and it wouldn't work. I one stage me and a colleague went through a tutorial on it in sync and the same steps would work on one computer but not the other.

Had we got it working well we might have even saved this particular company (mostly a graphic design one), they were in the advanced stages of circling the drain. It's frustrating when you see the potential of huge productivity improvements but their just out of reach.
