I would like you to implement a very simple (boolean) option at the search transferlist panel, where you could simply ask for players on the NT (U21 and/or AA).
A simple checkbox would make a great diference for me
because I'm used (sometimes) to manually search on the NT Ranking page, team by team to see if teams got players on sale.
Since players on NT are atractive for many reasons, from being proud to giving money, I think it would be a relevant addon ;)
