Documentation/tutorial?

I just installed this add-on, and wanted to create an empty group and start moving tabs into it.
Instead, when I clicked "Create Group" it grouped all the tabs in my window.
I'd like to back out of this situation by ungrouping all the tabs and starting over.

Is there an easy way to do so?
How does one manage a single tab, so that it isn't closed but is no longer part of the tab group?

Some sort of tutorial video showing how this add-on works would be very helpful!
