Anisotropy can be merged into Settings (better name for that tab may  
be Parameters)
Also Analysis can be merged into Outputs

so it could be
Inputs   Outputs   Parameters

and Markus is right - guisection is missing for elev, it should be  
added here

189     parm.elev->description = _("Output surface raster map  
parm.elev->guisection = _("Output_options");

and for maskmap as well (that should be under Inputs tab)

If you could change this it would be great (I won't have time until  
weekend to
do something about it)

thanks a lot


P.S. using -z instead of layer=0 is a great idea, I will look into it
