Right, exactly... Right now just needed a way to archive flows. But, should I need more, you gave me an excellent question to ask or idea to consider.
I think somewhere in the forum, is how to trigger the hosting browser to initiate flow download was documented. I think is what I recall seeing in the past...

Since I added an input text box to set a persistent path for the export of flows to the NR host system, figure I might as well allow export to browser host file system as an option as well.
