Export as a video
Have the option to share and export as a MP4 file. This would make using and sharing important videos easy with other.
And also export heatmaps as JPGs.
This is something really hard to implement. What I can do is provide an option to give a link to a specific recording.
You could actually export is as an MP4 file by recording your screen while playing back the visit (using a software like https://www.screenr.com/)
