A wish list was a list of items one wished to obtain.
In 2152, after attending the IME Conference, Doctor Phlox returned to Enterprise NX-01 with a wish list of medical equipment. (ENT: "Stigma")
In 2373, Crewman Pechetti prepared a wish list of items to salvage from Empok Nor for use on Deep Space 9. The list had three categories: "Must Have" (e.g. plasma manifold systems and plasma recoilers), "Could Use" (e.g. EPS matrix converters), and "Would Be Nice" (e.g. bypass displacers, polarity maximizers, and Cardassian emblems and insignia, the last items for Pechetti's personal collection).
