One table for a collection that lives in several places
Most collections are not one pile. There is the loose binder, the cards currently sleeved into a deck, the trade stack and the box of things you keep meaning to sell. Tracking them separately means never quite knowing what you own.
Collection merges every list you keep into a single table. Each row is a card, with the quantity you hold and coloured chips showing which of your lists it sits in, so you can see at a glance that the three Sol Rings are one in the binder and two in built decks.
