Windows: We all let our open tabs get out of control sometimes (or that’s what I tell myself to feel more comfortable about the chaos). If you ever need to move multiple tabs to a new window, select them all by holding down Control and drag.
For some reason, this trick doesn’t seem to work on Chrome for Mac, but in Windows, you can hold down Control and select multiple tabs in the same way you select multiple files in Explorer. Then, simply pull them out and create a new window, or move the tabs to another existing window, exactly the same as you would with a single tab. This is just yet another trick that’s probably been around for a while, but we never knew.
