Thank you, and that's a great idea I've considered for future releases. More specifically, the layout presented in this video looks ideal: https://www.youtube.com/watch?v=HybzbDBF7HQ. Where the screenplay can replace the letterbox at the bottom.
One of the reasons we decided not to implement that for now is to provide a bigger room for error since our algorithm is still not perfect. Sometimes the extension choose to focus on 1 or 2 sentences next to the accurate dialogue. Having an entire viewport height to show the screenplay means even if some inconsistencies occur, the user may still be able to see the accurate dialogue.
