Is there any way to remove the file name tab in InDesign?

[PEGShane]

I'm talking about this tab, above the pasteboard where it just shows the file name and then that whole area is emtpy to the far edge:

If I could hide that it would give me a little extra viewing room, which is important on my laptop.

Thanks!

Uncheck the 'Open documents as tabs' box in the Preferences, then maximise the document's window:
