Javascript Intellisense, finally!
It looks like Visual Studio 200n (aka: Orcas) is finally going to have rich Javascript intellisense, hurrah!
Why, oh why wasn't this implemented in 2005 and I'm not saying that for any reason other than a purely selfish one. If I'd had rich Javascript intellisense it would've made the project I've been working on for the past 6 or so weeks massively less painful!
