Make a video to illustrate the use of the GUI
We could quite easily make a video showing how to use the GUI and how to navigate on it. Several softwares that allow for capturing the screen exist. In addition, I installed and used the ShotCut software on my laptop. This permits to make video editing. It is quite easy to use and very powerful.
For doing that, we would need to write a 'pitch' of what we want to show, what we want to say. We would also need a good microphone. And maybe someone with a better accent than us for the comments. :)
