how to set a skin view only for movies or TV

hi,

probably a stupid question .. but can’t seem to find anything about it in the wiki.
there are some skins that have a lot of nice views. But sometimes I see that a certain view is selectable under TVShows but not under Movies.

Where do I edit ..or where do I start looking to change that ?
Want to try editing a skin myself a bit .. and wanted to start with a view that I like under TV … and would like to copy/edit for Movies.

tnx in advance
