Grey sidebar on navigation is permanent and takes up screen space - PLEASE GO BACK TO OLD INTERFACE
Please remove grey sidebar and reintroduce fully hideable side bar - like in older versions
Previous versions you could hide the side bar completely and be left with a small arrow on top left screen to reopen side bar - this worked well.
New update now has a pointless grey side bar which is PERMANENTLY THERE and requires multiple clicks to access and reduce pages notebooks etc
Not only is it annoying and pointless, this takes up precious screen space.....please change what you like but having the ability to have a whole text screen free from waste of space is fundamental, simple and absolutely necessary.
