I heavily use this program to manage card lists with an overall of +110k cards.
I 'loose' a lot of time splitting stacks/card piles to move them to another list.
Would it be possible to 'walk' through a list while moving cards to another list, asking the number of cards to move (suggested amount = previous amount).
This would speed up list manipulation.
I would also like the option to subtract a list from another one.
When I sold a 'wishlist' to someone, then I can easily update my list with remaining cards.
When a card is not found, a warning may be given (preferable a summary list at the end of the operation).
I'm also open for other suggestions to easily manipulate lists.
