worthy widget: TypeCast
I’m still not 100% sure that OS X Widgets are a great idea (I tried Konfabulator over a year ago, and it was trashed before the end of the afternoon) but there’s one that’s come close to making me a convert: TypeCast.
It’s simple, big enough to be useful, and provides single key movement throughout the entire font library with a custom line of text or the full alphabet: it’s now trivial to discover the right feel without having to wade in with FontBook. The most stunning aspect of it is the speed that it manages to achieve when full blown apps just bog down.
If you use fonts and have Tiger then do try it.
