This is awesome. I developed Chrome/Firefox browser extensions that connected Gmail attachments with cloud storage in the past, and hacking through Gmail's DOM always threw any SLA we could provide out the window. It's even better that this will run on Android and iOS as well, which truly makes all the "Gmail extensions" from developers such as myself production-ready.
