It is hard to pin down the author's bias, or yours, without understanding what kind of development the author has done. I look at this as more of a Text Mate 2 vs Sublime Text 2 post.
Thanks for explaining this, b/c editors I use (albeit inside IDEs) all do what the OP is drooling about. I figured he had to be comparing Sub 2 with some other editor that he doesn't specify.
