Basically everything in MC's Library operates at the "file level". Levels above the "file" are all metadata tags, not physical database entries (in almost all cases). The file is the "atom".
Given this, the MediaCenter GUI is basically
views.
When someone posts that they need to do something in MediaCenter, the reply from MrC, Marko or Glynor most of the time is a
customized view often including an expression, based on MediaCenter's internal expression functions and/or regex.
This has some really great advantages in that you can group audio, video or image files in any imaginable way.
However, to do anything past the default settings requires either being a professional (or amateur) computer programmer - and spending a lot of time studying the view system and the expression functions, or else having the aforementioned very helpful Beta Team members do it for you.
I have found that other software, including other media players, bridge the gap between those two situations by having people export (and upload) their setups - just the same way that MC does with skins and plugins.
The reason this is effective, is that a thousand different MC users don't actually want a thousand different setups. They just have a different subset of tasks they want to do.
For example, most MC users have no classical music. In contrast, MC user Vincent Kars wants an MC view that is right for classical music. He wants "Composer" to be prominent, as well as "Work" ("Piano Concerto No. 3").
I am sure that when Vincent is finished, it will be just fine for my own classical music listening.
So, instead of both of us (and many other MC users) having to spend many hours doing the same thing, it would be helpful if Custom Views can be exported and uploaded, just like Plugins and Skins.
At that point, all those Views become Features of MC. A reviewer can then say "And you can download an excellent Classical Music View to setup MediaCenter just right for classical fans."
Seems a win-win to me.
