RFE: Add a button to undo split

Submitted by Elad Alfassa Link to original bug (#747003)
Description
Sometimes I work on on multiple files in multiple panes, and then I want to hide the other panes and focus on the main one. It would be nice if between the two "move" buttons there would be one that would change the view back to one document only, without having to "close" the other documents.
