Piwik 3 announcement - the vertical menu

I’m reacting to the Piwik 3 announcement I’ve received in my mailbox today. Congratulations.

There’s only one thing bothering me with the good news: the first screenshot still shows the vertical menu.

I firmly believe that the menu should be redesigned and receive some treatment, for instance, with a visibility toggle or it should be made collapsible. I can’t see what justifies the wasted screen space below the menu. I remember some debate about the menu switching to vertical, but I haven’t followed the subsequent discussion on that subject.
