The main things that jump out are the inconsistency in writing style (sometimes doing all lowercase and no punctuation) but then the brief rundown is all perfect spelling and grammar with em-dashes.
The "Not just" parts stick out like "Not just play them back — edit them" as well as "This isn’t a proof of concept or a weekend project. It’s a real authoring environment."
Anyway, best of luck to the author with their project!
