[FEATURE REQUEST] Replace (in game) Card Viewer pane with Graveyard view

I'm not sure how many people are using the card viewer, but feel it may be a worthwhile enhancement to use that pane as a view of the graveyard and eliminate the floating window for the graveyard.

Start by locating the in-game card viewer pane and the floating graveyard window mentioned in the request. Determine how those two views are connected before deciding whether the pane can replace the window. Done means the graveyard is available in the former card viewer pane and the floating graveyard window is eliminated.
