Is there a tab group plugin for Chrome that works like Simple Tab Groups for Firefox?

Looking for something that isn't "smart" and which doesn't load up my URL window with pseudo-URLs.

What I like about Simple Tab Groups is that it lets me create dozens of groups and select the active group via the plugin's menu button so it doesn't clutter up the header. It should also (of course) let me move URLs between them and auto-save.

This is for Mac Chrome.
