I have a bit of a conundrum. The alternate source that I am looking at contains 128 different categories. That may be historically correct, but not very helpful. I'm wondering if one could merge some of them. For example, 22 music categories? Wouldn't "Score" and "Song" be enough? Any thoughts on which categories that could be conflated (if at all)?

The categories are:

May I suggest you adopt the categories listed in The Official Academy Awards Database:
https://awardsdatabase.oscars.org/?search=Basic

You can then condense the various music categories under:
• MUSIC (Scoring)   <== original or adaptation (there may be multiple winners in the same year)
• MUSIC (Song)  <== original or adaptation

Other categories that may be condensed:
• WRITING  <== [includes original story, screenplay, original screenplay, adapted screenplay, etc.)
• PRODUCTION DESIGN  <== [includes art direction, art direction (B/W), art direction (color), etc.]
• CINEMATOGRAPHY  <== [includes cinematography (black-and-white), cinematography (color)]
• SOUND <== [includes Sound, Sound Recording, Sound Editing, Sound Mixing, last two discontinued after 2019]

Could there be some sort of way to export the list from "Collection"? I'd like to add it to Letterboxd or something to check which of the films I haven't yet seen ...

I'll consider it for the next version.
