As an editor I want to switch from editing content elements to add content elements.
• All “Add content buttons” are removed from the page view to save space.
• There is one button at the top that allows me to enter the Add-mode
• After a click on the button the view changes to Add-mode (formerly Content Element Wizard) which lets me choose a position and a content element type to add.
• The Add-Content-Element-Sidebar is opened in compact mode
• The Dropzones-Overlay is displayed
