It would be really great if the option "Preserve overwritten remote files to recycle bin" (as described at https://winscp.net/eng/docs/ui_login_recycle_bin) would also work for SCP (and eventually FTP). I think this shouldn't be too difficult. I really like to make backups of the files I've overwritten. Unfortunately many editors don't support such features and I thought WinSCP would be the ideal solution, but then I figured out that the option only works for SFTP at the moment.
Thanks in advance!
