Opening Dev Tools on VEXcode

I am trying to open Dev Tools (or a least load my own JavaScript) on VEXcode (not VEXcode pro) to add my own dark theme and customize a few things but I have been unable, I noticed the resources.pak file contains JavaScript but when I edit it VEXcode no longer opens I assume due to a checksum or something I have found out that VEXcode uses nwjs a framework for writing node.js apps for desktop if anyone has any ideas that would be awesome,.


Dark theme should just be made standard
