I would love to be wrong on this, as I think even without this feature, Immich is one of the best options available.

That said, I am referring to this feature: https://github.com/immich-app/immich/discussions/2836

If it has something similar, then I'll happily consider it. To me, this is one of the more advanced (and well-liked) features of a photo app, which is why I have it there to help differentiate.
