What is the workbench?

When I was editing a book profile I noticed the workbench feature listed in the right column. What is it for, and how does it work? I added a title to the workbench; now what? I don't see anything about it in HelpThing.

>1 houserhenry: The workbench is relatively new, so no one has written a HelpThing article for it yet. It's a tool to help combine works more easily. On any work pages you can click "add to workbench" which kind of sets them aside for later. Then you can click on "view workbench" and see all of the works you have added to the workbench. From that page you can combine all of them (or some of them) together.

I don't think there was an official announcement, but here are some details: https://www.librarything.com/topic/244878#5862943

It is very handy for combining zero-copy works into their respective many-copy works.

BTW, after finally getting used to it, I LOVE the workbench!
