is it possible to hide subflow runs from the prefect UI? We’re currently experimenting with flows that run many (hundreds) of subflows, and it inevitably clutters up the UI.

Hi @Mike O'Connor thanks for the question. It's not currently possible but I think we could add a filter to hide sub flows. There's an old ticket here that you can add to and I'll ask the team to re-triage and see if we can get it onto the backlog.
