The bottom bar in Writer has 3 buttons for multi-page layout mode: Single page view, multi-page view, book view. I believe it should be possible to choose among these from the View menu - not just via bar buttons. Otherwise, their existence is easy to miss when focusing on the menus for functionality search (and even when focusing on the menus-and-toolbars for functionality search). They also fit the purview of the View menu very well, along with Normal/Web, Zoom etc. The three could be placed in a submenu, so that only one additional menu item would be necessary.
+1, but dupe The status bar controls are in viewlayoutctrl.cxx [1] and would need new UNO controls to be able to add to the View menu. Or to customize assign as keyboard shortcut. *** This bug has been marked as a duplicate of bug 150839 ***
