XBMC exports and can import watched flag. Why do you need an addon for that?

<importwatchedstate>true</importwatchedstate>

Because that way, each user (be it at different profiles or different machines) that shares a media storage can have its own "watched" list mantained when files are moved. If you export your "watched" status each time you use xbmc (the best time would be right before going to sleep mode), whenever files are moved around, each user can get their watched status back. I think that is not possible with the export/import function of XBMC. Also, exporting everything (not just watched status) I think takes a much longer time.
- If you export to just one file, watched status cannot be got back when you move files (unless you somehow update paths in the exported file)
- If you export to different nfo files and move them to the new location, only the watched status from the user that exported it are mantained.

An even better solution would be to link the watched status not to the file itself but to the IMDB/TVDB id, so, if you get a different version for a given movie/episode (for example, better quality or in a different language), it will still be marked as watched when appropriate. I usually have, for some tvshows/movies, one version in original language and one in spanish, and sometime (whenever I can, to save space) I substitute both for a dual version. Unfortunately, then the watched status is lost (in my installation, 5 different people watches media with his/her own profile and/or machine)
