At work yesterday, I had a thought. I hate calculating the Difference in values between keys.. It's not hard, I just hate having to open the calc to do the math (cause I'm lazy). So, to further my lazyness, I figure I will add a neat little feature that displays the curent value of the selected key and the difference between the selected key and previous key and the difference between the selected key and the next key.
Any additional thoughts or add on requests are still welcome.
