@keithchong wondering if you have time to take a look at this. I plan to give it a thorough review to get this into 2.7, but that may be ~4wk from now. And I don't think I have the React chops to review the frontend well. :-)

Just encountered a bug.

1. In the Manifest tab, add a parameter with array: []
2. Switch to the Parameters tab and click "Edit". Without making any changes, click "Save."
3. Switch back to the Manifest tab. array: [] will have been replaced with map: {}.

We need the UI to keep track of the fact that the empty parameter is array-type instead of map-type.

[crenshaw-dev]

Where the tooltip currently says "This parameter is provided by the plugin," could we add "It has been overridden in the Application manifest" where that's the case?
