SFTP split screen for move/copy operations

[isontheline]

Hi,
it would be great to have a "split screen view" for move and copy operations, allowing us to keep 2 tabs open in 2 panes, it would make copy/move operations in SFTP much faster and smoother. This UI could be triggered by a button or by rotating the screen landscape and should allow us to select which connection to keep in the open tabs and copy/move files around by dragging.
See the attached gif from a similar app to understand better what I'm trying to explain.

This could be related to issue #57.
Thanks
