I came across a feature he other day that came in really handy and was wondering if there is a plugin for InDesign CS6 that could accomplish a similar effect.
In MS Word, when you go to Font-->Font Collections, there is a dropdown menu with a list of the fonts I have loaded in the categories I specified in FontBook. For instance, when I loaded my serif fonts into FontBook, I put them in a collection called "Serif." MS Word then uses this information and has my fonts organized into my specified folders. Bascially, it allows me to separate my fonts by style, ie. Serif, Sans Serif, Slab Serif, Retro etc. See attached image to get a better idea of what I'm talking about.
It's a nice idea, but Adobe is (understandably) reluctant to add platform-specific features. There is no equivalent to Font Book in Windows (at least, not as comprehensive), and also nothing like the Font Collections.
Microsoft doesn't seem to worry about non-transferable platform features. Perhaps you could first convince them to make something similar like Font Book for the next Windows
