Does the tool support paperback, case laminate, and dust jackets?

Yes. The Cover Maker builds all three binding styles:

• Paperback (perfect bound) — the standard softcover wrap.
• Hardcover case laminate — art printed directly onto a hardcover case.
• Dust jacket — a hardcover jacket with front and back flaps (the tool gives you flap copy fields for the teaser and author bio).

Each has different geometry — a case wrap and a dust jacket add wrap/hinge allowances a paperback doesn't — and the tool handles that math per binding. All bindings for a book are covered by one cover license.
