I hapen to be found of Stress Detection, but then again I'm a new player myself. It frustated me before not knowing when I would have one shot left in asking a question. Now, as long as I know I have all of the alibis accounted for, I can always ask the townspeople for their notes.
I fully agree that having a full suspect list first is a good idea. I once had to quit a favor case because I couldn't find the motive. Frustrating like crazy.
