I like how your system can convert a document into e-learning. My focus is on IT instruction of systems, etc. My questions are as follows:

I didn’t notice it, but is it possible to not have AI images when generating the course? I feel I would get better mileage to do the images separately using Ideogram, editing in Canva to remove items and replace text.
For audio narration, can I adjust the timing of the audio if I add it to a slide?
For say, a podcast, can I add this audio to the slide with a player?
Any way to lock or hide layers so as not to keep selecting the wrong item on canvas? For video, I was in design and preview mode and did not see a way to use video controls. The main audio control in the menu at the top doesn’t mute video audio?
Change the opacity of the background to make it less prominent.
Thanks. Richard in the UK.
