Currently I'm renting some of my players and I've noticed that it is hard for me to check whether or not they've gotten experience, because for that I have to check every game of the player that rented them and then I have to check if they've set them up. I don't know if it's possible but perhaps it's an idea to add an xp tracker, in this way you can see how much experience your players have gained and then you can better decide whether it's a good idea to rent certain players off or not

(The main reason to rent off players in my opinion is to give them extra xp, since not all players can play, the main reason to rent players is to get affordable players for a certain period of time that play well)

Let me know if this is possible and if this would take too much space!
