As of now when you go to a player's name and then to ad/update. You will see a pull down, not sure why it is located just there. Several members would like it in other places.
On the pull down there are lists:
All, Haves, Wants, For Sale/Trade, in-Transaction, In-Transit and No Status.
Before the No Status was made the Wants had all your wants and other cards of the player that you have not marked. Now the No status shows only all the cards you have not marked in Haves or Wants.
The plan was to have a Do Not Want list also, but Admin stated that is farther down the road. Then we can put cards we are not interested in (so 1/1s, var) in it and we will not see them on our want lists or No Status lists. Not sure if he would have them on the ALL list.
As stated above it is Only in one area. Several members have brought it up wanting it in other areas, but I do not know if they have put in a new feature request. Like you filter a card by notes and then just look at your Wants.
