Grouping tabs

How do I put tabs into a group?

Drag one card onto another and hold it there for a moment. A colored band appears around them both — let go and they're a group.

To add a tab to a group that already exists, drag it onto the group and hold. To take one out, drag it out, or use the card's Remove tab from group control.

Groups are Chrome's own, not Clearing's. Anything you do here shows up in Chrome's tab strip straight away, and anything you do there shows up in Clearing.
