I guess I don't understand what makes this Electron specific. It looks like a UI kit similar to Bootstrap and others. Maybe it's too early in the project, but some mention of how the Node portions of Electron are used would be helpful.
Yeah it looks like an attempt to create a UI kit, which I think is helpful for those who want to work with Electron without having to actually design their entire interface. I imagine it will get better overtime and become fine tuned for Electron in specific.
