>> editor that works well for most stuff.
Wow, you're the first person I've heard that from.
Even hard core WPF guys who love writing XAML code hate the VS editor because it's a funky hybrid that does neither XML editing nor visual editing easy.
There's not even a real clean way to just get a plain XAML view (without the designer which keeps crashing because it can't render the XAML). You can open as XML but then there's no Intellisense.
The VS story for XAML is dismal and a disgrace for Microsoft IMHO given that WPF has been out for almost a year and a half now and missed the boat on a new release of VS.NET that just shipped. And from what Microsoft hints it's not going to get any better. MS suggestion is to use Blend if you want better support which is OK, but the integration is still pretty bad between VS and Blend.
