Thank you! I'd prefer it to be faster too, I sort of rushed this one out as a POC. The next one will be a tighter.

I used Final Cut Pro, but tbh I didn't like it very much. I'm going to try Premiere next. I recorded it in IntelliJ with the built-in mac screen recorder (QuickTime). I used a plugin for the presentation-mode theme, but I've since got a new computer and I can't remember the name of it right now...
