Video tutorials

Dear pyFAI users,

The ESRF management is pushing to get more video tutorials.

Currently, there are already few tutorials on pyFAI:
* the calibration with pyFAI-calib2: https://www.youtube.com/watch?v=hqp0UyvepXk
* The calibration within jupyter: https://www.youtube.com/watch?v=j0cphX3z2mM

Which topics would you like to see addressed by such video tutorials ?

Thanks for your input
