Looks good other than the error handling and translation todo. Nice work!

I was going ot merge this but then I noticed there are a handful of missing translations to fix.

Do you want to take care of that before I merge?

@DanRibbens undefined translations have been fixed 👍

I tried to test the feature with blocks and it errored for me.
This was taken from our test/localization suite working with the Nested Arrays collection.

I'm not sure if this is because the collection has versions enabled or if it was nested data that couldn't be handled.

Aside from this, I have UX concerns about this feature as it would be too easy for a user to click the wrong locale and overwrite some existing data. It feels to me like we should have a modal or something to add an additional step for acknowledging that they might be overwriting everything in a document on the target locale.

The copy button should look more like a secondary actions with dropdown options like this:

Changes made:

1. Fix copying any nested or relationship fields
2. Improve button UI
3. Add confirmation modal before copying
4. Redirect to new locale

Ah sorry I didn't manage to get this feedback on the last review.

I found another issue with the feature. If you have a document that has 0 localized fields, we still show the copy to locale controls.

I found two more issues while reviewing this. Pardon me if you're still working on these details, thought I'd better share while you're still working on it!

1. When I copy with nested blocks it is no longer erroring, but the data doesn't copy in a blocks field. The locale data is just empty in the target locale after a "successful" copy.
   Before copy:
   
   After:
   

2. When editing a doc with drafts enabled, I don't have the Copy button.

Hey @DanRibbens these two issues are fixed and PR ready for review!
