Suitcase was always the mainstay of OS9 on Mac, and we continued to use it into the OSX era, but a couple years ago we stopped using Suitcase and started using Font Book, the built-in OSX app. It took some getting used to, but I prefer using Font Book now. It seems simpler. It copies a set of the fonts to your user/Library/Fonts folder which can easily be deleted. I like that.
Suitcase had the feature of loading fonts temporarily, which seemed handy when dealing with different versions of the same font where reflow would occur when using the wrong version of Helvetica, for example. Not really useful enough to keep using Suitcase.
Also Suitcase had the ability to open fonts automatically when using the plug-in for your app. This may be handy for some, but I prefer to load them manually.
Any other reasons to not use Font Book?
I would like to have an app where I can quickly scan thru the same character in a number of fonts to help match a font or get something I like (without using the online font guessing sites). Or browse fonts based on style, i.e., serif, script, etc.
Is there any app out there for that?
