Thanks for the kind comment! Yeah, browser APIs have become a lot better. Between bugs, different behaviour from one browser to another & unusual limitations, there's still a bunch of ways that they're not "all the way there" yet, but I expect that it will continue to improve. Unfortunately the biggest limitation right now is that only desktop browsers are capable of this. Browser vendors seem to have held back the APIs from mobile versions of each browser. I think they're just being cautious about rolling out something that could be bad for users, though. Hopefully mobile browsers will catch up once the vendors are confident that users can be adequately informed about what's happening on their device.
