It would be nice to have the possibility to export the view state of the Tag Cloud, like there is for Bar chart etc.
I think a lot of analytics and the gathered data is about sharing the data with other people as such it would be useful to do that. Maybe we can in general use a solution to be able to export any displayed data as screenshot by using something like http://html2canvas.hertzen.com/ (captures rather blurry screens on Retina displays and screenshot might not be 100% accurate but maybe there are other libraries or maybe some browsers support it natively. It would be ok to have this generic feature only in browsers that support it IMO).
WebRTC might allow to capture screenshots: http://www.webrtc.org/
