I'd like to request a feature to have the temporary file name be the same when opening a given file for editing.
For example, the Vim editor will remember things about your file (bookmarks, folds, debug tags, etc) when you close the file. If you open that file again, it will restore your bookmarks etc.
However, WinSCP creates a new temp file each time you edit it i.e. something like ".../scp12345/..." the first time and ".../scp67890/..." the second time. This ruins the ability of the editor to "remember" things for you about how you want the file set up for editing as it thinks it's opening a new file every time.
So, ideally, WinSCP could have some kind of setting whereby it would always use the same temp file for a given file path on a given host.
P.S. WinSCP is *awesome*, thanks for making it!
