Add a Book
Bookcases & Shelves
Organize the Whole Library
Pick a strategy to see how every shelf should be set, library-wide — books can move to a different shelf, not just a different spot on the same one. Each shelf's current book count is treated as its capacity. Nothing changes until you apply it — re-shelve physically to match, or click Apply to save it here.
Fine-Tune a Single Shelf
Pick one shelf and a strategy to see a suggested order without touching any other shelf.
