The current default layout Layout with the main toolbar Here is how LibreOffice Writer looks after removing the toolbar and only keep the sidebar located on the right. To achieve that result, set View -> Toolbars -> Standard unchecked. The benefit is a more focused and uncluttered layout without distraction and also more touchscreen friendly. It will be nice that user interface layout will be more responsive depending the size of the screen. This example is made with LibreOffice Writer 18.104.22.168 running on Fedora 23 Release Candidate 3.
