I really was not that excited when I heard there was going to be an interactive debugger where I could step through my code. Since I managed to find the bugs without it. (Of course, I did spend a LOT of time looking through the testing log!). However, it is certainly worth your while to watch the video and get comfortable with it. (this should take much less than an hour). One of my fav. features is that as I step through a process, line by line, I can see ALL the rules that are triggered for each process step. My 2nd fav feature is that a grid opens up showing ALL the BO's in context with the ability to see the value of all of the attributes. This helped me find a bug in the ways RegularUser was being updated that would have taken a LOT more time without.
