More event notifications

I feel like the option to choose which notification events a browser will display would be super useful. Inbound, Outbound, Answered, Missed. There is already a browser notification for inbound calls. This would be useful because it would make it easier for browser extensions to act on these events. As of now I have to deploy a backend to register a notification channel and then use websockets to communicate to the browser extension. If the app.goto.com app would use browser notifications for more events the extension would be able to hook into the notifications and act on them. That would be soooo nice.
