Had to dig this one up...but we did it!
This addition is working Nicely and has been a big help.
Is it possible to add that the sold price stays there and doesn't just go blank once the player is sold?
You can click in the managers page that bought the player and then click on the transfer list and then look for the player to find the sold price, so it's not like it needs to be hidden.
It would just make it easier when you have multiple bookmarked players.
Thanks
