I'm considering Hoefler & Frere-Jones webfonts for a new project. The service looks great but I haven't signed up yet. This may be different once I've paid for something, but for now their web preview kind of sucks. (sorry H&FJ) I want to test my own text before making such a big commitment but they only show their own promo text. To fix that I created a little bookmarklet that adds the 'contenteditable' attribute to all the preview spans. Now you can click any of those lines and type whatever you like. It's been helpful to me. Enjoy.
Drag this to your bookmarks: H&FJ Webfont Preview Use on pages like this: H&FJ Knockout
@codingdesigner Hey, that's handy! Mind if we borrow that & add something?— Hoefler&Co. (@HoeflerCo) July 10, 2013
