Add any member of bigger font families
600+ fonts is one thing. But the ability to use multiple fonts from one font-family would be the real thing! Wizzards at Webydo, the google webfonts-connection you've made works like a charm, but it's just... not ready without the choice of every font from within complete families.

I want to use Webydo for a project - however the font I need to use only comes from fonts.com or myfonts.com (Gill Sans) neither available from Typekit or Google fonts.
For me this is one of the main deciding factors in deciding what web building application I use. A font 'close to' for my clients is not good enough.
Although rare, perviously I have also designed a few custom fonts, which were produced by small independent foundries such as Parachute Worldwide. Ideally I want the flexibility to use whatever font technology/source I choose with Webydo.
