Quadruple mode display

Having the window divided into four sections (showing four folders) instead of just two would be so helpful. Can this be done?

Not in one lister, but you can save two listers - each with dual panes - as a layout. See here

Yes, I am aware of this. I have two listers saved, each with a dual display. As I work, I want all four folders (both listers) to be visible in separate panes. As a result, the main window would be divided into four sections. Is this possible?

@ztwersky Unfortunately no
