This was suggested on the JupyterLab call just now, but also applies to cocalc. In Firefox and Chrome (but NOT safari), there's a + after the last tab, and clicking on it creates a new tab. For CoCalc it would open the +New page (exactly the same as clicking +New), so would be very easy to implement.
