I see a button "Faces" in the bottom bar, that looks quite natural to me.

Yes, in the main photo.db the tables
FaceTable (id, name, time created)
FaceLocationTable (id, face_table_id, photo_id, geometry)

Well, nothing to be done here but improving the underlying libs.

As far as I see the code only rectangle shapes are supported, but
import could be done, as the FaceLocationTable contains in the
geometry column objects like:
Rectangle;0.681;0.816;0.125;0.12
which should be able to be created from the information in Picasa.

Well, then someone has to write an importer .... that is the big question.
