Hey,
Personally I wouldn’t suggest using it even if it did exist, slows down the menu huge I know someone here at work likes having that turned on in MS Word, It chugs when you pick fonts.
I would just use Extensis Suitcase, it has a nice font preview for all your font sets, nice searching features. Have all your normal, heavy use fonts activated and when using other fonts browse through and temporarily activate them as you need them. It also installs a slick plugin for quark, illustrator and indesign which auto activates your fonts as you open files up. Helps when you have 10,000+ fonts. I’ve been converted from ATM.
Cheers
