It would be super helpful if I could add notes to a player. If that were to happen it would also be great if there were one place I could see all of my saved notes, but it's not necessary. Aside from that a place for general note keeping would be good as well.
E: As a new player and a very dedicated slut this would help me keep track of accounts and highest payers between the three different machines I use throughout the day. Also let me know who has helped me outside of business transactions.
