Dual pane in portrait mode
Split screen in portrait mode like the one in FX file explore. It's really helpful for single-handed use to copy/move files between folders and to/from USB drive.

I'd like to see the dual pane in portrait mode for tablets too, but side by side, like SE looks in landscape mode. On Samsung tablets it would greatly help with multiwindow in portrait mode.
