Many of the VS2012 videos in this series make an assumption, in my opinion, that a potentially brand-new user knows how to bring up the first screen in use as the video begins. Why not take a few seconds up front to pull back and say - "here's what we're going to talk about; here's the mouse clicks you need to do to get to this screen I'm about to start demoing for you"?
This is the second webcast from LangNEXT I've listened to, the first was WinRT. I am very hopeful that for the next LangNEXT someone will bring a microphone that is capable of recording the human voice at somewhat higher fidelity than what can be achieved with two empty soup cans with a taut string stretched between. When Alexander Graham Bell said the first words "Mr. Watson - Come here - I want to see you" over the telephone in 1876 it was better fidelity.
Hi regarding the question posed in the video: Page Inspector default window behavior, I think my vote would go towards the default being a docked appearance. Then as along as there is an easy way to undock it and have it behave like a browser window (which will typically be most helpful for devs who have a dual monitor setup I would guess) and then redock it, I think you would have a very nice story with that.
