I do the same, with Nextcloud though, but I doubt SkyMarshal would consider that as an enhancement. He, and others, sync it manually and "offline" for security reasons.
You can use any kind of sync software you prefer, be it cloud-based or local LAN-only. At least with cloud-based it’s not a glaringly visible honeypot with a huge target painted on it.
Setting up local automated sync is on my todo list, it’s just lower priority than too many other things. As I mentioned, I don’t create new accounts so often that I need automated sync.
