I would second cleverjake's comment that a neat way to see serveral fonts together would be awesome (Especially for a different headline font vs the body copy).
Also, a search for the big list of fonts would be handy too.
Off to a great start though, thanks for sharing!
It will be added in the next version. Pinky promise!
A little ashamed to say that I haven't used it yet (I'm a developer more than a designer, so just haven't had the reason to try it out properly yet. I guess you shouldn't really need a reason to experiment though!), but it looks gorgeous and a really useful tool to have.
"You don't have a compatible version of Flash installed. Please install latest version of Flash and refresh this page."
Webfontloader[1] uses javascript to detect whether a specific font is available. They use a hack where they change the font of a piece of text and calculate whether the width has changed, indicating the system is using specified font instead of the default serif or san serif. If you had a large list of fonts, you could filter out the ones the user has.

You really need a better fallback than NOPE these days when it comes to flash.
Edit: Had to enable flash in order to make it work
I was supposed to add code to change fonts with up and down keys but it was getting a bit complicated for JS noob like me so I dropped it for now.
It'll be added in next version for sure.
Also has a bookmarklet so you can test them on your own site.
I'll have to dig more into the code which detects fonts but I hear you.
