It would be nice to select multiple tabs at the same time so I could move them to a new window more easily.

Use-case: I often start a new project and open a bunch of tabs, then quickly realize that my window is running out of space for tabs. I want to take these tabs and create a new window with them. These tabs are almost always adjacent. I would like to go to the first tab, then shift click the last tab to select them all, then drag them off to a new window.
