I'm not sure how many people share the same thoughts, but I have two feature request to discuss
1. Sync media status between PMS
People are having more than 1 PMS running at home, so could we sync the playback state among the servers?
2. Migrate metadata from one PMS to another
Similarly, I now running PMS and have much media data stored in one PMS, but I'm gonna to buy a new PC to replace current PMS, how could I copy all media data along with the correct path/state info to the new PMS? One thing PMS I love most is the various movie and TV show metadata and pictures, so I don't want to redownload all metadata and pictures from beginning again.
FYI: if you use Trakt, the watched/unwatched episodes/movies are synced between servers.
I only recently started using this but it seems to work. I guess one needs to play with the options (sync intervall, etc.) but so far it seems to work.
