Hi Jim - thanks so much for showing me this! It is definitely an improvement. And thank you @DBear for the code about vimeo videos. I'm about to work on it all and it looks really clear. I'll post here if I have any questions or issues, though. Thank you so much!
I'm open to better user interface design. I'm also trying to figure out proper responsiveness of the title (1st) scene elements and the subtitles with the audio - so that it is large enough and looks good on desktops' browsers and mobile devices. As well as a few other things like making all text be the same font size and be responsive. right now the text size changes. I'll make another thread for this when I'm ready, but if you or @DBear have any immediate suggestions, that would be great! Thanks so much.
