Comment 2 for bug 42926

I think that in the long run, there might have to be made a font manager for Ubuntu that is able to turn collections of fonts on and off. So you could have a "default" collection which includes system-imperative fonts such as Bitstream Vera Sans, and a "miscellaneous" collection for all fonts besides those, which is disabled by default. All new fonts that packages install would be automatically thrown in an "installed by packages" collection.

This is a simple but great way of managing fonts, but I doubt an idea like this could be done before the release of 6.06...
