Hide the 'grouping' bar?

[9cupsoftea]

It would be nice to have the option of hiding the grouping bar - the one with the album art size slider and the sort by artist/album etc. For me most of those options are one-time things, and I imagine a lot of people aren't using it frequently enough to warrant taking up space. I think there are so few things you could even merge it with the address/search bar somehow, or at least the option in the layout configuration should allow hiding it.

i've added a right click command to hide the header - it shows as 4px hight with the top part of the panel layout button still visible so you can unhide the bar, or choose a panel layout command
