For now iCloud is enough and I don't get the extra hassle to support that too. I run but only out of curiosity the calendar, CardDAV/Contacts, etc services.

Web Station: if nothing else then to ensure that DSM doesn't listen on HTTP 80/HTTPS 443.

Mail Server/Mail Station: as a mail archive for emails forwarded from Internet services (set firewalls to only allow SMTP in from those Internet servers).

VPN Server: if I didn't run VPN Plus server on SRM router then this would be it.

DNS Server: run an internal server so that I can access devices by a simple name and also bypass Internet resolution for my home domain.

That's nine and I can't decide which is the last one:

Hyper Backup: all the data needs protecting off-NAS.

Docker: for those unpackaged applications that are useful to try out and/or keep.

unix and setup commands that I'll forget.

Note Station/DS note: For recording stuff like a note/scratch pad.

Synology Drive: Works for my needs and is enough original Dropbox-y now that Dropbox is bloated and a client resource hog.

Moments: I'm lazy and just want something similar to Apple iCloud/Photos.

Video Station/DS video: cos the family finally use this in preference to iTunes library content (cos I stopped updating that).Plex*: because it works well and tags easier than VS.Media Server*: music serving to my HEOS devices.Audio Station/DS audio: it can stream direct to UPnP/DLNA speaker and Airplay (hey even my Airplay 2 Apple TVs are working again when PIN access is enabled), plus Casting.

Is there a windows desktop heos app
