Well, the author had a habit of promising tons of things without being able to actually do them (a bit like Blizz did with dance studios/aerial combat
). Not malevolently of course, I can imagine that he wanted to do a load of cool stuff but just never got the time/money for them.
It took him ages to get LUI v2 finished after a couple of months of "it's next week". I bet this put a lot of pressure on him, and it's very possible that he's tired of the constant nagging for patch updates or LUI v3.
Edit: Damn this post is messy. But I'm sure you get the point.
