I like using the software called Scripte.  It makes my notes tidy and clear (see samples on their site).  I was an assistant editor many years ago, so I am very particular in my notes.  I want them to be as helpful and clear as possible for all who read them from the UPM, POC, Editor and if a commercial the agency personnel. I love the time code and still frame grabbing features.  I’d be happy to help any of my fellow scripty friends learn about it.  Just give me a call.
