Okay, thanks. Was just checking in, as realized this is on an older site; newer site is in MapPress latest.
Not sure if others would have this need, but we are working with relatively complex KMLs for which InfoWindow content is crucial, and it’d be tedious to manualy re-add. (In other cases users want to work with KMZs, including e.g. images, which also would not be immediately supported in MapPress without manually editing.)
