Clean and efficient output is my biggest gripe with many of the current builders.

I would like to add:

- good multi-language support

Internationalization is definitely a big one. It's a hard thing to do right for a website builder designed for non-technical people, though.

That being said, I'm proud to currently have customers that have built sites in over 5 different languages, that I know of.
