I love using isort!! I usually do this right before code hand off as it gets annoying to deal with the import conflicts. Is there a way to automatically use this like we use black? I've been wanting to integrate this for a while.

I've added it to our test-and-lint GH action so we should see an error on any commits that don't conform. Should work well with black now and be enforced in the same way.

Okay sounds good!!
