After the fifth time today of right clicking on one card and a different one being discarded something dawned on me. I'm not sure how difficult it would be to code this, but would it be possible for the cards selected to be discarded to slide up to off set them, and then a discard button?
It would be slightly clumbersome, but a slight shift in your mouse and you lose your powerful item card you were going to cast, and since it's the only copy you have it's a little fustrating.
I agree. That would be a very nice improvement to the interface. A quick second click to confirm wouldn't take long, especially compared to the 30 seconds allowed for a turn.
