You can place a card at the bottom of a deck by holding right click and sliding it into the deck.

This feature is height challenged and stops working below a certain height. I think this is because lift height also bottoms out. The main playing area is below that height, only barely too.
That made me find out that the side drawers are very far below minimum lift height, which just has odd behavior. I really wouldn't be surprised if there are other related issues in this area.

Raising all the components of the table to y-40 seems to be make everything work, including on the really low drawers. It puts the rim of the table just above camera clipping height, but i think its worth doing, since it allows right click to properly slide objects on the floor of the side drawers.
It also fixes the issue someone else had with the card regions being too high.
