How to have mix "movies" + "shows" in one folder

[Venson]

Ok to be totally frank with everyone: I am a big supporter of getting rid of the mix lib type. In essence, nobody from the current dev team _wants_ to touch it, there are lots of issues with it for many people and it creates both a noticable impact in support requests and lots of confusion in addition to frustration when users come here or the chat and ask for help and nobody will help them.

Not long ago after some particular troublesome help requests i formalized the idea of getting rid of mixed libs.

For example I'll pick Star Wars - there are lots of movies, TV series and a few specials.

Love this example. I was initially going to say Breaking Bad, Better Call Saul, El Camino.
There's also plenty of similar content in Au under the "Underbelly" umbrella. Seasons, 2 part mini/movie series, feature movies.
Even an actor folder, i.e. Paul Hogan. He initially had his own comedy TV series, + other movies before & after Crocodile Dundee. Why have it scattered.

My sons just turned 22, wasn't interested when this stuff was on (incl GOT). His about to motorhome around Australia, setting up a nas for him.
I could tell him before he leaves to make sure he watches the others, that their in the other section, but doubt he'll remember when the time comes.
But if there all in the same folder....

So how would I set this up? Movie & Shows library option, pointing towards;
>Breaking Bad Series
>>Breaking Bad
>>>S1
>>>S5
>>Better Call Saul
>>>S1
>>>S6
>>El Camino

Sort the Series into 
Series/Breaking Bad/Season 01
Series/Breaking Bad/Season 02
Series/Breaking Bad/Season 0X
Series/Better call Saul/Season 01
Series/Better call Saul/Season 0X

And movies into

Movies/El Camino

To aggregate them in the UI, collections are the way to go. How its stored and how its displayed are two different things and have two very different requirements.
