Quite okay, but lacking crucial features

The app does exactly what is described above, and nothing else. It quickly copies all contacts to Google Mail, maintainig the lists I assigned them to. But I expected a bit more, since this is version 3.2 and should be more than just a proof of concept. Please add at least a way to select, which groups should be synchronised, instead of synchronising all by default. E.g. I want to sync my private contacts (groups "Private" and "Familiy & Friends") but not my business contacts to my private Google Mail account (and vice versa). With that feature I would definitely give a 5 stars rating.
