For newer users a quick design option in the (Object Spacing box) for simpler signs would be great. We typically space lines of text using 1/2 to 3/4 of the text height used. If the program could do this automatically with a slider button that shows what the sign would look like at 1/2 spacing to mid spacing to 3/4 spacing. (This could also be set up as a percentage spacing option.)

Arrows and route markers typically can have less space, so the same type of spacing automation would be great, but maybe use a certain percentage less than what is used above. Like -35% less space of whatever numbers the 1/2 to 3/4 space turns out to be above.
