I miss a #virtualFS (#openvfs)approach like nextcloud, dropbox and onedrive use on Windows. In best case it is independet usable on all kind of network storage like sftp, nfs or smb.
I miss,
- the possibility to have auto cached network files
- the possibility to have some files or directory permanently in sync

I hate it that a linux laptop even with VPN is not able to stay connected to a network folder especialy if you work with hibernation.
