Sorry for not looking at this sooner. Happy with the changes (and in general with the other PRs as well). Only thing I wouldn't do is remove the lines between the extends and the class documentation. I think having the class documentation separated makes it easier to read.

(though I get the style guide states differently, one of the few things I don't like personally :) )

Done! Re-added space after extends, and removed documentation comment for private methods. Also replaced exclamation mark with not keyword. Don't know how I missed that the first time.
