Feature Request: Browser Notifications for goals

You know those pesky websites that ask you for permission to send you notifications about irrelevant stuff in your browser?
How about putting the Notification API to good use? I think beeminder would be an excellent choice for this. This way one could have notifications on the computer, too.
I could imagine that many users prefer this over email notifications from Beeminder Bot.
For instance, I close my mail client during most of the day to not get distracted.
I would want something important such as beeminder notifications on emergency day to still make it onto my desktop and kick me in the parts so to say.
