Create new tab group if tabs don't belong to any tab groups.

Hello.
I'm grateful to your extension.

I would like to send request to add feature.

I had wanted to reduce the cost of making tag grouping.
I hoped to create the tab group automatically.
So I added the feature to live out this as a option.

If user checked this option, a new tab group is created when a ungrouped tab create a new tab.

This extension might not need this option.
Even so, this would make me happy :)

Please consider.
Thank you.
