Well the website is complete enough that I don't need to add anything apart from some good use cases (Tweet/Comment if you have other ones!):
- Find which plist gets modified from a particular setting
- Find what files get moved/installed/removed when doing something such as installing Chrome
- See if a process is doing stuff behind your back
Just a word of caution: Packaging is hard, try not to if you can. Sometimes, pushing the original package with a Configuration Profile might suffice. Also, events might get dropped if there's too many. That's by design from the Apple API.
