German users might also be interested in the AdNW layout (http://www.adnw.de/). They started out with Neo’s excellent and logical arrangement of the non-alphabetical layers, but replaced the alphabetic layers with a layout created by running an optimization algorithm on a text corpus of 50% English and 50% German text (whereas in Neo the key arrangement was created manually, based on intuition). The metrics they used were largely inspired by Dvorak’s research.
