So it's just the website in a chromium wrapper? So I'd be downloading ~50mb for something that I already have in Chrome? I'm trying to find a feature it has that I can't get through Chrome...
An individually dockable app with a badge icon showing unread messages?
For some odd reason I couldn't get the badges to work well for gmail though.
I know you can have separate Chrome users, but this may separate concerns slightly more. Not sure.
