I like Tab Scissors: https://chrome.google.com/webstore/detail/tab-scissors/cdoch...

Splits your many-tabbed Chrome window into two windows at your current tab. Useful for when I open up a bunch of tangential research pages and want them in their own window.

You can kinda replicate this functionality by shift-selecting the tabs you need to split and drag them away.
