Jesus this is absolutely <i>brilliant</i>.<p>Occasionally I do sites for my business partner and the endless tweaking of fonts to get them how he wants is a pita.<p>I can throw this at him and he can give me back the CSS, fantastic!.
This has huge potential for us as a way of quickly making styleguides reducing both development time and designer QA time.<p>There are some important things missing, as far as I can tell though, like ... how do I make a list?
I see you have support for Typekit as well. Very cool.<p>This is pretty damn awesome, I have to admit. One of the big pains of working with web font services like Typekit is that you have to select a set of fonts beforehand, save the kit, change your CSS, and only THEN can you see a change. At best you can keep a handful of browser tabs open without refreshing them so that you can flip between them to compare. But this makes everything so much easier.
Great concept and good implementation.<p>One bug report - The font selection scroll bar becomes hidden and un-clickable for me often in Google Chrome 30.<p><a href="http://imgur.com/6nohjWD" rel="nofollow">http://imgur.com/6nohjWD</a>
