We removed the tiny, hard to click "open" button on tabs. Now, you can just click anywhere on a tab and open it. Hold SHIFT + click on the tab to open it but keep focus in your dashboard. Or middle click (Click with the scroll wheel on your mouse) to achieve the same thing. This works on saved tabs, currently open tabs, and previously visited tabs in past sessions.
