Highlighting files (i.e. colorize) by type

New to Opus, and I really dig it; however, I can't seem to find a feature that motivated me to find a prog like Opus - changing the color of filenames based on their type (extension).

Opus has every feature imaginable, and I would find it very odd if it lacked this one. Anyone able to fill me in?

Settings -> File Types. Edit the File Type of your choice and click the Advanced tab.

Thank you.
