I'd love to be able to select when to update my trade list. When I receive the cards is later than ideal. It means I need to remember what cards are meant to be in the mail to me currently. It'd be great to have a button in the trade window where I could choose to do it now.
I'd likely do it much earlier than currently, the number of failed trades is low so re adding my wishes when a trade fails is much less effort than remembering what is inbound. Maybe just having the 'pending trade' icons actually work would be good enough. Currently they pretty much just don't work.
