Nope, apparently quick load doesn't load several IDE features at all. What I mean by lazy load is that it should incrementally load the IDE features after the IDE starts.
Jeez, the obvious optimization would have been to load some of the features first and then load the rest, but to not load them at all? That's not very useful.
Well, as a back-seat commenter I agree with you but they probably had a good reason to not do it. Most likely something to do with development complexity. There's a ton of smart people working on Visual Studio, I'm willing to trust their judgment on this :)
Well, they definitely had good reason, it's just that the feature isn't very useful without the extra work. Although, I don't know exactly how much functionality is missing, so I might be wrong.
I seriously hope they add a lazy load feature in the future.
