When I go to choose a font, I am confronted with a bewildering choice of hundreds of fonts, most of which I have not downloaded and many of which are in foreign languages I have no use for.
In Mac’s Font Book, you can create collections, which would be a way of winnowing out everything you don’t want. But is there a way to invoke that in SU? Without it, you just have to remember the names of fonts you like.
Probably most of those fonts were shipped with the OS or came with other applications. SketchUp and LayOut don’t come install any fonts at all. You could remove those fonts you wouldn’t ever use.
