I see that; what would still be useful is having the information displayed. Even when ordered that way, you still have to click on the card or the "grading recommendations" button to verify the amount. If I am sorting by "grading profit", I would like to see the grading profit displayed.

This would be an excellent addition. Being able to sort my card collection by potential PSA 10 would help a ton with establishing which cards I may want to have sent away for grading in the future. There are some cards that aren't worth having sent away when they enter the collection, but in 5-10 years, they may be worth sending.

Not having to check every single card manually would save a ton of time, and make the overall experience much more user-friendly.
