I have an idea for a plugin for Anthologies/Box Collections/etc. that would allow you to save metadata/cover image for the anthology alongside the metadata for a book/story split off from the anthology.
Whenever I buy an anthology or box set, I will split it so that each book/story is a separate book. (Mostly because a lot of the anths. I read have stories that are part of a larger series and I want to be able to read those shorts in order with the series without having to search through anthologies to find them).
So basically, I want to add an additional tab to the metadata editor that allows entering meta about the anthology, it would essentially look the same as the basic metadata tab, but would be additional info about the anth instead of the specific book.
Is it even possible to make changes to the metadata editor window?

I am aware that I can add custom columns and add the info in there, but I would like the functionality of being able to download the meta like the way the basic tab works and to add the cover image to that tab.
