Graveyard Recursion

When casting a spell that targets a card in your graveyard - it would be nice if this automatically opened the window for your graveyard, rather than having to manually click it. (Though if there is only one valid target, I believe that gets automatically selected.)

I am pretty sure tutors automatically open the library to target a card.

For effects that can target a card in any graveyard, it makes sense to need to open the desired graveyard manually (especially in multiplayer games). Personally, I would prefer it to open both(all) graveyards automatically, but I expect my personal preference would not be shared.

Start by locating the client code that opens graveyard windows during card-target selection, then compare it with the existing library-opening behavior for tutors. Done means valid single-graveyard targets open the relevant graveyard automatically, while effects targeting any graveyard still allow the player to choose manually.
