We would like to see more Flow APIs in order to automate Flows :
ex. start a Flow from an external app, stop a Flow, get a specic Flow status, copy a Flow (to another environments),import/exports flow,dynamically generate a flow...
Based on this API the community (or MS) could also provide Powershell cmdlets.
Copy/move a flow to a different environment!
cmdlets to move flow or update definition will be very helpful
