Yes I think copying the destination is probably the correct default for softlinks.
I tried a shortcut and rclone does ignore them at the moment with a DEBUG message like this
2020/03/28 17:57:19 DEBUG : file2 shortcut.txt: Ignoring unknown document type "application/vnd.google-apps.shortcut"
So that is probably the first thing to fix. Would you mind putting this into a new issue on github for me so I don't forget? Put a link back here - thanks
