Hmm, ok, I tried that, and the command hung without logging anything to the terminal or terminating, and /mnt/jack101 ceased to be a folder, and became a binary file - one I didn’t have permission to access
aarvi@fedora:~$ rclone mount jack101: /mnt/jack101/ --network-mode
Honestly default GNOME is probably less confusing than this for old people, and even less confusing once you customise it a little.
Seriously, this is good effort! But anything based on XFCE or Plasma is going to look technical and confusing.
