Hey guys, thought you'd be interested to know about this. I've pretty much spent the last two days solid coding this, I'm making it because of the upcoming dogs of war mod and also to replace the old and buggy one. It's a very much more refined and (hopefully) smoother xml editor. I'll put it up when it's finished and this post will probably turn into a feaure request/bug report zone as well.
For now, if you have any features you feel were left out of the original and should definitely be put in this one please post that here too.
I'm also wondering if I should make a GAE version too? I was also thinking of making one to do LUA for scenarios
