layout.panels
'auto' pushes the document aside at comfortable and switches to an overlay drawer at compact and below. The sidebar — one panel, with Pages, Outline, Attachments, Signatures and Comments as tabs — then floats over the document, and a backdrop appears that dismisses it when tapped. Force either behavior with 'push' or 'overlay'. On a tablet the sidebar always docks beside the page.PanelDisplayModedefault 'auto'
