As for the ability to switch off the film strip, I contacted FMP about it, explaining that it gets in the way, especially when you're using a laptop. Their response emphasised the value of images (which you may feel to be patronising) and then said:
So I definitely think that the designers sat there with their big screens and couldn't see any issue.The option to turn off the page navigation tool you mention is not possible. We will continue to monitor its usage and any feedback we receive.
Your feedback has been logged with the Product team involved in this launch.
Please folks - feedback that it gets in the way if that's what you think.
