Awesome^3 !!!

Provide information to the user to suggest fonts that will work well together

With a tool like www.fontsquirrel.com/fontface/generator we could usually sigificantly reduce Font-Filesizes and improve Speed.
If f.e. only versals are needed, we could reduce filesize to less than a quarter of the Latin1-Size!

To divide space evenly between menu items in a menu, I need to measure it's width. But the width changes before and after the @font-face has been applied. It would be useful to have callback functions or events which Javascript developers can use to hook behavior.

Some of us might just want to use a few fonts on one website. You should a consider using a price per font system.

I've look into it and found no Khmer (Cambodia) language supported. There are lots of demands in our country, so it will get popular among us shortly.

I can't find any information on your website about the migration from FontsLive to Fonts.com Web Fonts except for a single blog entry. The blog entry & the email I received left me with a lot of questions that I'm sure others must have. It would be useful to have some information in the Help section.

I couldn't figure it out just browsing the fonts, so I signed up, only to discover that the font I want to use is only available in the paid plans. So I gave out my personal information for nothing, and now I can't find a way to remove it and delete my account. If I'm just overlooking these important details, I apologize, but otherwise, this has not been a good exercise in brand trust.

I.e. So that when I get to the bottom of the page, I don't have to click next page.

Why can I just buy a license for the font, and use it on a site? Your system is incredibly complex to use, when using font-face is very easy. The way I need to assign weights is insane, I need an expensive license to test locally for just a small blog. Isn't your service a DRM "has been" system that can't live with his time?

I found that your Simplified Chinese Fonts only got GB2312 or HKSCS character set. Which means I can't use these fonts under a CJK (Chinese Japanese Korean) mixed UTF-8 situation. I hope there will be some UTF-8 fonts

Fonts appear differently depending on the contrast between the background and foreground colours. It's important when choosing a font that the designer can understand how the font looks when on a dark background.

Please add sort button (default alpha sort) for Project page tabs for Selectors and for Fonts

For "complex" scripts (Arabic, Devanagari, others in the future...) it would be good to deliver fonts with AAT tables to browsers on OS X. Currently, the Devanagari fonts do not render correctly in Safari, and some of the Arabic fonts also fail in the Results list even though they render OK when looking at individual samples. Similarly, Firefox 3.6 fails to use these fonts because of the lack of AAT support.

Majority of Simplified Chinese fonts seems experiencing major loss of characters. I suspect that you might have mistakenly replaced traditional Chinese fonts for Simplified ones, as those that are lost are those that are different from Traditional characters.

Removing the number of requests would further speed up the page display and reduce flickering (font change while rendering)
