How do I collapse the tab ribbon?

I now have 5 rows of tabs in the tab ribbon of the C3 editor, and it's taking up a lot of editor real estate. I use all of those tabs on a regular basis and don't want to remove any, but it would be great if the tab ribbon can be collapsed when not needed. Something like the "collapse the ribbon" feature in Microsoft Office would be great, or a click+and+drag feature where you click on the bottom of the ribbon and drag up to collapse a certain number of tab rows.

Has this been discussed, or is there a way to do this already?

Thanks

Done. Glad I'm not the only one, let's see if we can get enough votes.

Thanks

Voted, thanks!
