Another themed list, PT:
In PT, Show Lowest Sell Price for Each Card in Collection Missions -
JudP mentioned this, but I've wished for this for awhile too.
In PT, Allow For You To Set A Sell Price For Multiple Players -
JudP mentioned this as well, but it's something I've wished for too. It'd be similar to the auto-sell function in the settings screen, only that you could set it for specific cards, not just any cards under a certain rating. It'd also be best to be able to tell it whether you want it to sell every copy of a card you have, or only duplicates.
In PT, Show Overall Rating on "Your Card Orders" Screen - Despite the card title, some times I have so many card orders I forget what card they are exactly and seeing the overall rating would help tremendously.
In PT, Allow You to Sort the "Your Card Orders" Screen - Again, some times I have so many card orders, it would help to be able to sort that screen to more easily find the order I'm looking to check/update.
In PT, Show Exact Last Sales Data the "Buy Order" Screen - The "Last 10" never seems to change so I think it's often less than the last 10. But even better, I'd like to see the actual last 10 sale prices with their time & date.
In PT, Allow For You To Set How Many of A Card You Want to Buy - For speculation purposes. Say, for example, you think the live Mookie Betts card's rating is going to go up to the next level with the next update, you'd like to buy as many of them now as you can afford to sell them later for a profit. Yeah, it won't happen, but some people would love it.
In PT, Quicksell at Highest Buy Price - rburgh posted this and I think it's a great idea. Only change I'd say is that the buy price must be QS/0.9 to make up for the tax and prevent those QS+1 buyers from getting it.
