Hello,
I would be very happy if that feature would be added to Enpass because this feature to sync locally is still missing.
At least the folder sync could be added to the mobile versions (ios) so the possibility of syncing to a folder on a synology nas or other network storage system would be given.
web dav was not an option for me because it is a horrible thing to set up. (also it is again something to be able accessed externally and not JUST local)
