    I gave Drinfel’d double an Idea-section.

    Also moved a paragraph on module categories from the References to a Properties-section.

    I have an objection against moving the center construction to properties. Namely, the center of a monoidal category is really the idea of the Drinfel’d double, from the modern perspective. So if a Hopf algebra is obtained by the Tannaka reconstruction from some monoidal category, then the Drinfel’d double is the reconstruction from the center of that monoidal category. This perspective (by Majid) also enables to do beyond the finite-dimensional case.

    So you want to have it in the Definition-section then? Fine with me. But it was in the References section before! :-)

    Never mind, once I am back to Majid’s book I will edited properly to have both generalities (and the dual version, also called Drinfel’d double).
