If you’ve followed along with the leaks in recent weeks, none of the new features will surprise you. It’s also not a huge surprise that Google is bringing some features from Inbox over to Gmail. What did surprise me while trying out the new service ahead of today’s launch, though, is that some features that didn’t get a lot of attention in the leaks, including the new consistent sidebar with its built-in Google Calendar, Tasks and Keep integration, are maybe among the most useful of the additions here.
