Group by set, fold binders, and a phone layout
The next round of collection improvements came from thinking about how collectors actually sort their cards.
Group by
Group your collection by binder, set, or game, or by binder, then set to see each binder's sets inside it. Every group shows its card count and value, and folds away with a tap. Search opens any folded group with a match, so nothing hides.
Real card number order
Sorting card numbers as plain text puts 100 before 99. The collection now sorts them the way they're printed: 6, 25, 199, 200, with plain numbers before gallery and promo cards like GG05, TG12, and SWSH050.
Sets in binders
I considered binders inside binders, and decided against it. It adds a lot of complexity for something most collectors don't do. Instead, a Set filter and Move to binder cover the same need: filter to a set, select all, and move it into any binder you like.
Built for phones
On a phone, each card is now a compact block instead of a wide table row, so there's no sideways scrolling, and group headers stay pinned at the top while you scroll.
