TypeJet for Mac

From Chronopath, Inc.:

TypeJet is ArcaneWare's superior and fast font viewing utility, built to improve your creativity. Find the perfect font for your logo or project in minutes, rather than scrolling through menus multiple times to view every one of your fonts. TypeJet provides you with many of extensive features to find that perfect font. One of those features being multiple font sets, to put your favorite fonts into different groups, or to take aside the fonts you used for a certain project. Not only are there the manual font sets, but there are also "Smart Font Sets". You can program one of these font sets in seconds, and get great results. For example, you can make a smart font set display all and only Helvetica's, without having to manually add each one. With smart font sets, add a new font that applies to the smart font set and it will instantly update that set. And here's yet another way to find your fonts: TypeJet has a live search feature, which gives you instant results! No more scrolling to find Skia. Better yet, if you are all together tired of scrolling, use TypeJet's slideshow! Set a timer interval in the preferences and hit "Start SlideShow". And for getting your maximum out of the application, go into full screen mode. Preview every font in any style you wish to use. TypeJet is the easiest and fastest way to view fonts.
