I saw a new trick to me, you might like as well. When out working use a "dry erase marker" to take reminder notes. You can write on all windows while out working, then wipe clean later.
Used to drive demo for JD with the S series. 680 and 690 are my favorite machine. High capacity because of the active return (compared to 670). Unfortunately never run one in corn. Only wheat and canola. Open concave wide & high fan speed and you will love the capacity with minimal losses
