Just installed this add-on and finally!! everything works as I'm used to. Now I can include/exclude with a simple touch of a button, use subprojects, sub sites and everything else that worked in VS.NET 2003. I don't understand why you had gone into such major changes, when things don't get easier but get worse. And I consider myself advanced web developer.
VS 2005 has numerous great features but managing complex/advanced web projects was not it's strong side, thanks to this update things changed.
So thank you for making the things the way they should be in the first place.
Although it comes a bit late (just spent a week changing projects back and forth to make my 2003 projects work) it is still great!
