How do you hide the "Left Main Panel"?

[TheIronKnuckle]

I recently reinstalled musicbee to fix a bug, and it reset all my settings. now I can't work out how to get the "left main panel" to go away. (It's the one that lists albums and has album art).
This panel is a useless waste of screen space and is pissing me off. Previously (prior to my reinstall) I couldn't see it but now it is stuck there refusing to disappear. I know it's possible to get rid of it but I'm not sure how. Any pointers?

Go into layout settings and turn off the thumbnail browser.

What setting is it exactly? The only thing I can see is "thumbnail browser:" with the following options:

1. Small thumbnails
2. Medium thumbnails
3. Large thumbnails
4. Don't show thumbnails

I've selected "Don't show thumbnails" and now no thumbnails show up in that panel, but I want the entire panel to disappear. I can't find the option for that

Do you see the option for "arrange panels"?  If you open that window, you can remove the thumbnail browser completely.
