I would love to see a background option to be the desktop. That way we can place our face on top of a CMA and talk about it.
Are you Mac or PC?
We do have a desktop app for Mac that allows your webcam to show on desktop activities.
PC is in the works
Also are you Gmail or Outlook?

You can send yourself the CMA as an attachment, then preview it in the browser and use the chrome extension there
