Probably the key on-set invention of the talkie era is the role of script supervisor, of the notion of keeping track of continuity and the continuity script, which records in code each take, its length, and differences in lens, exposure, subtle details in continuity (when a sip is taken, which hand holds it).
Strangely she left no records, was rarely if ever interviewed, and her invention was overshadowed by her own ability as a writer and her domineering husband who took credit for her work.
Notice the Columbia link makes no note of her core contribution to the film industry.
That Wikipedia page is self-contradictory about the script supervisor/continuity role, saying that she invented the it when sound feature films came in and also crediting her with it in movies 10 years before that. This one says she invented it in 1918: https://en.wikipedia.org/wiki/Script_supervisor

So why post the Columbia link with such a different and misleading title? See here: https://news.ycombinator.com/newsguidelines.html
