Actually, on the subject of specifying ecps, a small query for the developers: how difficult can it be to modify the logic of the parser (or whatever it is that interprets GAMESS-US style input files) so that one only has to list ecps for the elements that require them, rather than all the atoms (and in the right order). A minor thing I know, but it would make inputs simpler for large molecules.
