How to load mainWindow.loadUrl from settings?

[akashnimare]

Great app. I have built a electron app on the top of this demo. I want to load the URL from settings.html. Currently I have to add the Url manually but it should be user defined. How can I do this? I am having hard time figuring this out. Is it possible to have a mainWindow.loadUrl = somevariable and load it via input value of the field.
