Update notification for unpacked extension?

[jhildenbiddle]

Since unpacked extensions do not auto-update, it would be nice to see some kind of notification when a new version of the extension is released. For example, the extension could check for the latest version on GitHub and inject a notification in the viewport when loading a medium.com URL (or any other URL the extension unlocks) letting the user know they need to manually install a new version.

Without this feature my guess is most people will be "notified" after the extension stops working, which is a less-then-great experience.

Thanks!
