Tutorial to help you create Current Shows system. It is set to show series that you have been watching during last 30 days and show only episodes after the last watched episode. The difference between previous solutions is that this one also handles re-watches as marker is set whenever you watch any episode.
1. Create new Series relational library field EpisodeLastWatched (see attached image)
2. To set progress marker(season_episode and timestamp) for series add following to your After playback expression (tools => options => expressions) :
If(IsEqual([Media Sub Type],TV Show),SetField(EpisodeLastWatched,[Season]_PadNumber(ListItem([Episode],-1,-),2);Now()),)
Now when you finish watching an episode (e.g. Wire S01E04) your EpisodeLastWatched value for all the episodes should now be something like: "01_04;44933,7142939861878403"
3. Create new View for series or adjust your old one (Example Standard View attached)
To filter series/episodes in the view use this to show only series which has been watched during last 30 days (you can adjust range to whatever you like)
[=Compare(FormatNumber(ListItem([EpisodeLastWatched],1)),>,Math(FormatNumber(Now()) - 30))]=1
...and show only episodes after the marker (everything after 104 for the example)
[=Compare([Season]PadNumber(ListItem([Episode],-1,-),2),>,Replace(ListItem([EpisodeLastWatched],0),_,))]=1
NOTE: set to work only with seasons/episode under 100 (padding needs to be increased if show have more than 99 episodes per season)
NOTE2: handles double episodes e.g. 1-2 (or 01-02-03) notation
NOTE3: for client/server setup also client needs that "after play expression" addition as unfortunately in MC that is not in server's responsibility but all the clients need to set it on their own and remotes can't set it at all
