This macro helps with opening the stacked decks in the inventory. It only opens the first row in the left of the inventory. You need to go to the menagerie or the delve to be able to open and not erase the cards. After some cards are dropped to the floor, it's necessary for you to move to another place because there will be a lot of cards on the floor and you'll not be able to drop any more cards. Works in 1920x1080 resolution.
