From Josh Steelman:

I like the feature you guys added to basically take a snapshot of the rendering window, but could it be made to take a shot of the entire MAEviz window, so that legends could be captured as well?

It might be useful for the time being to offer the user two options, screenshot of the entire MAEviz window and of just the render window. Although, a user could just use print-screen to accomplish the former. Ultimately, I think this could be solved with richer reports, where screenshots & legends are displayed to show the meaning of certain visualizations.
