[REQUEST] Trakt.tv: Sync/Update collection status

[jensb89]

The only thing I'm missing from MrMc is the collection update of the trakt plugin/service.
After a library update, new episodes/movies should be added to the trakt collection (cmp. the trakt plugin for Kodi).
This means, the Sync collection API should be used (https://api.trakt.tv/sync/collection/) additional to the scrobble and movie/epsiode sync.
Would be awesome, if this would be implemented :)
