Even though last changes and bookmarks may usually help, sometimes you just want two or possibly more views on one document. This is where split view are priceless feature. Amy Editor allows for more than usual two views allowing splitting your document into unlimited (actually limited by screen size) separated views for easier editation. It's not that uncommon to work on two, three places of document at once. Another view is simply activated by clicking on the first left icon of the status bar. Only one view is active at the moment, and this is the view to be split when clicking. If you want to close the view, use left icon on its split bar. Split bar can be dragged to change connectect views sizes. You can alternative close the view by dragging split bar outside of the document area (same as throwing away Photoshop guides).
