Realtime preview recording/export

It's great to be able to export a time lapse of a drawing, but it would be super awesome if it would actually reproduce the image in real-time (that you can then speed up), i.e. instead of the image just kinda appearing bit by bit as it does currently, it actually shows lines being drawn, colour being scribbled in etc. so it would negate the need to film yourself drawing it from your phone and doing that whole video editing process.

It would be a HUGE time saver for artists.
