I historically have never liked Electron, and I don't like it now, but unfortunately due to poor browser support, I don't have a choice to ship anything more lightweight if I want to use the Filesystem API as part of the packaged build, which is kind of the point. I guess it's true: "You either die a hero or you live long enough to become the villain." This is an experimental build.
