screen mode button is gone
Screen mode button has been removed from tool bar and there's no way to add it back in MUST HAVE SCREEN MODE BUTTON IN TOP TOOLBAR where it has always been in the past.

I'm agree it's really frustrating to have to go into a scroll menu to simply show your artwork's preview. I know there are already in the left menu, but for me it's not the place to be, it's not a tool, just like the zoom option.
