Serviio

I have a large library of TV Series for the whole family.
As I watch some that the other members do not, it can be difficult to remember what episode was the last watched.

Adding a watched / unwatched (and reset) indicator would be great.
This is a function that is available on the Apple TV. However our Apple TV is only connected to 1 of our 3 TV's .

i second your request

I agree with this!
I wish to update your idea. Four indicators are more than one. Adding 4 color flags would be great. There are four color button (red, green, yellow and blue) on every tv remote control. These can be easily change the flags. The meaning of the flags depend on us (I watched / on my watchlist / my wife watched / our kids watched / etc...), of course these flags have to set manually each movie or episode. The little four color flags fit right side of the movie date.

A question that must be asked: would you want this indicator across all renderers, or player-specific? I have a hunch that something player specific is beyond what the video provider can do, as it would likely require a separate table in the database to track every movie that each player watches. Not saying impossible, but give Zip an idea what you are looking for.

The colored flags may be something that has to be enabled in the player firmware. I don't know if Serviio can provide anything that can't be understood by the player. I don't know the DLNA standard at all, so I don't know if there's something that might allow this. Just knowing the differences I see in my various players makes me have doubts this can be accomplished across the breadth of players available.

As someone who dabbles in writing computer applications (I don't assist with Serviio) I think of stuff like this. My users would bring many great ideas, but implementing them was a different story!

There's already a "last watched" indicator for TV series; the last watched episode is shown with two asterisks before it's name.

Adding the date last watched would be better than just an flag indicator. I frequently watch the same movie over again if I haven't seen it in a long time. Simple implementation would be to append this date to the end of the title that's displayed. This way all devices would work.

I agree with this!
