Comment 14 for bug 1586678

I used Thunderbird for many years but grudgingly switched to Evolution awhile back because of this issue. IMHO, contacts and calendar sync should be considered an essential, core functionality for any application that manages contacts and calendars. Evolution's user interface is clunky as heck, but at least I don't have to pull out my phone every time I want to look up an email address.

Supernova looks great, but I think it's time to seriously focus developer attention on this issue. It's really way past due. If someone on the Mozilla team wanted to create fundraiser specifically earmarked for the development costs of implementing this feature, I'd happily contribute to that.
