center of projection at QTH, select all continents except your continent
center of projection at antipodes, select your continent (and adjacent continents)
Lat/Lon lines or Grid Squares
Lat/Lon lines at 30° spacing
grid square borders
grid square labels
grid squares to be filled with elevation data
(blank separated list of 2char grids eg FM FN EM EN case insensitive, takes about 2mins/grid,
elevation maps will be run at a lower priority than regular line maps)
fill lake (else border only - usefull if plotting filled grid squares)

Greyline by time/date (UTC not local time)
Sunrise Greylines at your QTH throughout the year
Sunset Greylines at your QTH thoughout the year
sunrise line and sunset line at QTH, for date below (time ignored). Lines will be close at equinoxes, separated at solstice.
Draw Greyline, date and time below
hour, 0..2359 (default == current time)
draw compass circumference (compass rose)
draw compass spokes (if compass circumference is off, spokes will go to antipodes).
Draw distance circles (has compass directions too).
