I would like to see a long standing bug fixed so that one could use Caja to copy files in a SSH or SFTP session and retain the original file’s timestamp. Please see https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/332646 - “when copying or moving files to a directory mounted over sftp, the time stamps are not preserved.” Judging from those subscribed to this bug, it is a very low priority item.
