I think it's important to separate the various suggestions the author offers from the actual implementation.
Currently, when my cursor is over a bracket, the matching one is already highlighted. I'd love it when in this situation his suggestion to color the brackets would 'activate'.
Or when my cursor (or mouse) is on a variable, I'd like to see the highlighting by type.
I can also imagine having a 'highlighting' bar somewhere on screen where I can switch between different forms of highlighting. When I'm doing a code review, highlight based on interesting conditions (long functions, lack of documentations, etc.).
