sub- and superdeck support

Hey all, first comment here, so please don't burn me 😄 I would like to suggest another field, called "superdeck", where one can see the highest level deck of the note. For example, if I have a note/card in the deck First Deck::Second Deck::Third Deck, it would show First Deck in this field. Because I have a lot of subdecks in one deck, it makes it kind of tedious to analyze them properly. Kind regards,
