The suggestion is definitely appropriate and reasonable, nothing wrong with the OP sharing their suggestion here. It is not too much to ask from Greg either if the below issue wasn’t there.
That being said I do not expect this to be feasible, mainly because of the reason why videos are non-downloadable on this platform. That is, security. If downloadable slides are provided, then they will be shared on the internet, and that is a problem since the main revenue model of GregMAT is from the $5 subscription fee. It may sound small, but there’s a reason why Greg would rather pay thousands of dollars for Vimeo rather than use YouTube for instance.
ehza is not speaking on GregMAT’s behalf, want to make that clear.
