ops! Forgot the list…
Hello Anna,
···
[…]
GUI takes the series of d.vect commands and turns it into a text file in format:
symbol color1 color2 size width textthe legend symbols would be always the GRASS symbols, so even line,
areas would be symbols. We would add new symbols for lines and areas,
for example straight and crooked line, some irregular shape for areas.
color1 is outline color
color2 is fill color
size is symbol size
width is line width
text is legend label
Would it be possible to also have font and fontsize for the text part?
so for example:
legend/line red none 5 2 State border
then each line of the legend will be drawn with d.graph.
[…]
What about the name?
d.vect.legend (like t.vect.list)
+1 (following d.vect.thematic and d.vect.chart) - this would imply to change d.legend to d.rast.legend perhaps
I can’t give any opinion regarding the most important issues, though… sooory 
Best,
Vero
