I'm automating a lot of my note taking and content creation through Obsidian and parsing the activity logs in Roll20 post hoc for the high points (it can be hard to take notes and run the game at the same time) is one of the longest tasks I have post game. Just having the Activity log as raw json (link at the top of the page would be enough, though a straight API call would be useful as well) would allow me to automate the majority of this piece and create a richer campaign for my players. I can immediately see several uses for this content other than my notes.
