Please describe.

Describe the solution you'd like

I would like to have a button to export heatmaps into picture file formats .png and .jpeg. It is really important for internal presentations as not all people in the company have access to Post Hog nor have the time to visit it. They just need to see a summary of some data in a presentation. It's important to have exported files also to track the users' activity. Pages can completely change after redesign and the only way to compare it's to have images before and after new features are implemented.

Describe alternatives you've considered

At the moment I am taking screenshots but it is really annoying as pages can be long and you have to scroll, take multiple screenshots and then combine them together using other software. While you do that you have to keep the same screen resolution and visualisation mode.

Additional context

There are some competitors that have this functionality, so I really hope you can get to release it soon!
Thanks
