Terminal is no longer draggable

[saadq]

I really like the look that's generated from your plugin, however it seems that you lose the ability to drag the terminal around when this plugin is active. After reading electron's docs on frameless windows, it seems that you can add a css setting of -webkit-app-region: drag; in order to make a certain part of the app draggable. Instead of going this roundabout way, I think simply leaving the header element in the CSS should work to keep the terminal draggable. Do you think doing so is fine, or is there some other reason why you needed to hide it?
