A small-but-nice quality-of-life improvement would be if pasting a full "YYYY-MM-DD" date into a year input automatically split it into the separate components and updated the month and day inputs as well.

I often run into this when I'm trying to propagate a live bootleg release's date from its title into "recorded at" relationships on the recordings. Right now, I need to manually retype the year, month, and day into the corresponding fields, which has the added bonus of making it easier for me to make typos.

I haven't looked at the code yet, but I suspect that there may be multiple areas that would need to be updated: relationship editor, release editor, artist editor, etc.

(See also MBS-1197 asking for a single date field, but I doubt that's ever going to happen. Maybe bitmap or reosarevok remember more from 13-14 years ago, though!)
