[Inkscape-user] Setting dimensions.

The default dimension setting for the marginal scales in Inkscape is in pixels which makes sense for most developmental work. But I prefer to work in inches, since my finished products (book covers) must be laid out very precisely in inches to get the spine to come out right. Of course one can create the components in inkscape and then stitch them together in e.g., Gimp, Scribus or even TeX. But I prefer to deal with the whole product in one program if possible. In Gimp there is an item in the lower left corner that resets the scales in e.g., inches. Does Inkscape have a corresponding setting somewhere?
