This is IMO rather an argument pro "reqno" setting: It would be a benefit to the users if LyX takes care of the requirements. We have the "requirements" framework in LyX, so this should be (relatively) easy to implement. > Moreover document classes that already don't use the default placement > have a special reason to do so.

The AMS provides the "amsart" and "amsbook" classes that are (in your above categorization) more "standard" than special "classes for journals". Both default to left equation numbers and (via the required "amsmath") provide the "reqno" option to override this default. LyX has native support for both amsart and amsbook, so special GUI support for "leqno" but not "reqno" seems inconsistent. Günter
