Show / Hide Interface Elements

Hi,

Thank You for all of the thoughtful improvements made to the interface recently.

As simple as it is, I have a request, It would be helpful to me (with limited screen space) to be able to show / hide the panels (I do not know the proper titles for them) shown in the image.

The bottom area Tag Tree panel I do not use much at all, the side panel showing Site Manager etc I use shortcuts for.

Thanks.
