They did mention that at least in the short term, the window shutters will
only be opened when needed. I think they are mindful of debris damaging
them. There is a lot of area there.

Jorge posted the "cupola rules" on NASAspaceflight.com. Evidently the
two forward-facing windows are to be opened only when needed, because
they have the lion's share of the debris impact risk. The rest can be
opened at the crew's discretion, except when a Shuttle is arriving or
departing (plume impact hazard.)
