This is quite awesome. I actually learned some stuff I didn't know. (especially camera centering - was one of my main PITAs with Blender and I didn't know there's a simple shortcut for that.) Most Blender tutorials are too newbie-oriented which ends up with me not knowing such basic, though very helpful features :p .

an awesome simple (once understood, what took me a few attempts) way to bend an edgeloop, working in a single face only:
