Feature ideas

Request for a top-level onWorkflowFailure handler, or a reserved finally branch on workflow definitions. Today, there's no way to reliably trigger a notification (Slack, PagerDuty, etc.) when a workflow fails without compromising the workflow's final status. The current options available are: onFailure: terminate — correctly marks the workflow FAILED, but downstream notification nodes never run. onFailure: continue — notification nodes run, but the overall workflow is marked SUCCESS despite the upstream failure. Impact: Can't easily implement basic alerting without misrepresenting operational health.

Requesting re-run button/capability for workflow runs. During development and testing, we have to create a new event every time we want to test a workflow change. Being able to re-run a previous workflow run would significantly speed up the iteration cycle.
