Once the map elements new bug is fixed in, I can easily add
at=5,50,2,5 to the d.legend command in the wxgui as the new default
(this could still be changed by the user subsequently). If everyone
likes it we can keep it. It looked pretty good to me--except for the
legend freezing and crashing the GUI. Need to trap that error and see
what it is.
6.4 still works fine.
