In the category ‘TV series’ it is possible to hide the seasons (which is for me more readable on TV), it is perfect.
However, Plex server knows which episode is from which season, and it doesn’t display it on the view, it would have been convenient to be able to see the seasons on the view of a series:
Example:
There are E1, E2, E3, etc.
It would be perfect to find the season in this summary: S1E1, S1E2, S1E3, etc.
This has already been discussed in this existing feature suggestion thread.
I suggest you comment/vote there in order to help us avoid distracting or cannibalizing votes.
