Font size and color can be set for point numbers and labels.

Peculiar increase of growth for that Norway spruce above!!! :-)

Font and color information can even be written into the .pos file and used when the file is later opened.
This is very useful when a coordinate file is used to set points and text on a map or on some other picture where the selection of a proper color is critical.
