Any idea how to get Inspect Element Working in this?
In newer versions: browser_settings.set_property('enable-developer-extras', True)

I tried to correct some of the formatting in this code (and tried to put it in this comment), this web interface doesn't seem to be preserving the formatting. I think I'll just fork it.
Here's the link to the fork https://gist.github.com/pydoh/2f1b8287276bb70d961e88842ebe741f#file-pybrowser-py
