Steps to reproduce the problem:
@rrkhayat on twitter had the good idea of extending the "capture screenshot with hardware" (see https://twitter.com/kaycebasques/status/738804397732306944)  feature to be able to record gifs

What is the expected behavior?
On the Device Mode UI, there should be a record button, or a record shortcut. When you press the button it starts recording your interaction with the device. When you press the button again it stops the recording and exports the video as a GIF (or whatever format is best). 

What went wrong?
Nothing... this is a feature request...
