Bar button should add current page as a dial to default group with one click.
The app button next to the address bar should be a one-click button to save the current page/URL as a dial to the default group. It actually doesn't make sense for the button to go the the new tab page since Chrome's home button does the same thing. Having a one-click add to default group is much easier than the right-click context.
