Nicely organized and presented

I love the different ways in which the fonts are grouped and organized. The "Usage" based search is especially useful for finding alternatives to particular typefaces, best choices for different applications (ie: web usage, small text) and sorting by time period (decade of release, or larger artistic movements).

This app has crashed once while I attempted to mark a favorite font, but even the best apps crash from time to time, so Im not going to penalize them for that.
