I would like the ability to customize the checklists for each set to include only the cards that I've chosen to collect (for example, I collect showcase cards, but not extended art). I would also like the ability to create a custom checklist for other collection goals (for example, I am attempting to collect all Planeswalkers, I would like to create a checklist that shows my collection progress towards this specific goal). Is this a feature that could be implemented or is under consideration for a future release?
