One of the greatest strengths of Scrivener is how much the UI will bend to your way of working.
For example, I currently spend most of my time using the layouts shown in this post, along with QR panels.
I use the Outliners to drive their respective Copy Holders, and have set Binder Selection Affects > None. That way in the Binder I can move files around, open/close folders, etc. , without concern of inadvertently impacting an editor.
I use the Binder to launch QR Panels (left-click > space bar) or to replace the contents of the editors (left-click > Alt+Shift+O for active editor, left-click > Ctrl+Shift+O for inactive editor.
Best,
Jim
