Split the active tab and all tabs to it's right into a new window of the same dimensions.
A simple extension for a simple need. Tab Splitter takes your active tab, and all tabs to it's right, and splits them off into a new window of the same dimensions as the original.
If you're like me, you often find yourself in a open-in-new-tab research spiral until you can't even see what the page titles are anymore, and feel a pang of regret for not starting a new window. Somewhere in there is a tab which starts a topic divergence which you'd love to have in it's own window. But doing that means opening a new window and dragging tabs about and... well, moving tabs around in Chrome isn't the easiest job.
This extension adds a button to your toolbar (sorry, extensions can't modify the tab context menu). Click it for relief from tabbageddon.
