Something less annoying to opt into web features would really be an improvement. Perhaps some "upgrade icon" next to that https lock icon? This already is the place were we take away the permission when we accidentally allowed some we did not want, and the "upgrade" would be somewhat parseable as all three of "upgrade to local(ish) installation", "upgrade to more site features" (push) and "allow more data upload" (location). All implicitly connected to the hostname.
