See two sections of the binder at once?

So I know you can split the editor to view two documents at the same time. I am wondering if you can split the binder, however, see you can see two different sections of the binder at the same time, presumably each with its own editor?

You can’t split the Binder, but you can use the Outline view as a secondary navigation aid, and you can create Quick Reference panes from either location. See Chapter 12 in the manual for full details on the (many) navigation options.
