One of the areas we've upgraded is the Fonts by Language options. Today we added Greek fonts as a separate category. We now have 25 different language/scripts that you can select from in order to refine your font searches.
Combine that with the ability to change the type sample string, and you now have a very powerful way to find exactly the right font to meet your needs.
We hope you find this helpful, are always looking to at ways to improve our site (so send us any comments !)
