Martin, can I request a feature.
In cases when I need to copy files from one folder ton another folder in the servers, Usually what I do is drag and drop them from right pane to the directory tree view on the left pane. The problem with that is I can't never sure what's the content in destination folder unless I click that folder and when I do that I lost my selections.
It would be nicer if we can open multiple WinSCPs and be able to drag/drop copy files from one another.
