@violetphoenix - Actually, that is not totally correct. When you use Ctrl + Shift + B (or from the main menu), a pseudo-sidebar is opened on the left. You still have to click on the "Open full Bookmarks view" link at the bottom to get the former complete bookmarks edit page. This is per version 71.0.3770.284
