I'm glad to see Quark picking up where Electrino left off, I'm very interested in those projects. However both of them are not production ready or even close to production. Plus now you're dealing with the same issues you get on web where you're coding for multiple browsers. However, if you're going to be using electron or similar then you're already used to that
There is also Quark[1] and and Electrino[2] that do this with branding APIs.
