This is the right answer.
Yes. But sometimes I answer the question asked, rather than dig into the underlying issue.
There are so many ways in MC to create a list of movies in different groupings that I could have written a book... but the real underlying issue turns out to be the capability and flexibility to do all those things, or at least a subset, in Theatre View via a remote control.
That's not going to happen, in any application, because a remote control isn't capable enough. Add a keyboard and an application may come close. MC can use a keyboard in Theatre View, sort of (numbers always get treated as letters like a mobile phone keypad) which helps. But there just isn't going to be a button for every function a user wants, and so there will be customisation of buttons required, and... like I say, a book.
Maybe some of those specific functions, like adding a movie to a list (a Playlist, but what's in a name) for later viewing, downloading subtitles, getting trailer data, rating, etc. could be added to Theatre View so that it works better for a family of adults and children. When I say add those functions, I mean add them in such a way that they are easy to access and use with a thought-out and probably a configurable layout. Just take a look at tagging in Theatre View. It is primitive.
Me, I just drop into Standard View and do what is required.
