I built the project on OS X and ran the following png export command

~> bin/plotly-graph-exporter.js '{"data":[{"y": [3, 2, 5, 3]}],"layout":{}}' -o out.png

The out.png image is generated successfully, but I noticed that the electron window pops up in front of my other windows.

Is there any way to prevent the popup? I'm concerned this would be a bit disruptive for eventual python/R users.
