XUL:IDE

There seem to be many projects around to create a development environment up for XUL. I was under the impression that most of the were dead, but reading in the recent days tells me that I wasn't completely right.

I call on developers of those tools to take a minute or two and describe what their tool is, which platform it has, target audience, development team, status etc.

Overall comments are probably directed best to n.p.d.xul.
