The card interface is simple and I understand it being a lower priority to more of the important aspects of campaigns, but add this to the list of suggestions for card support: The ability when playing cards on the map/table where when cards are played on top of each other they form a stack of cards which can then be shuffled/randomized. It'd probably be tough to implement on the table because a card played onto the table is just an art object, but a possible easier solution would be for the GM to select all the cards (using drag select) that you want to randomize and place them in a stack window which is basically an extra hand that isn't owned by a player in the game. That hand can then be shuffled and people (or the GM only depending on settings) can draw from it. Anyways, just an idea I had when testing out cards in a campaign.
