I've found some bugs but when disclosed ServiceNow is deflective and apathetic.
The answer is always either "this is not a bug and is behaving as expected" or "Yes this is a bug, but we won't act on it. You could submit an idea".
I've started submitting ideas, but I can't add a comment them listing the others so I'll keep track of them here for everyone to see (and upvote).
