Thank you kindly! I always try to put in little convenience features like this, I really dislike pixel hunting in adventure games.
Thanks for the feedback about the data analysis part, too. It's meant to be a bit confusing (i. e. you're meant to sort of guess at the mechanic as you're doing the "analysis") but you're right in that it's probably a little bit much. I'll see if I can make the Help section a little more helpful.
