The program allows you to color-mark a file, or add a label to it, or use a combination of a color and a label of one of the following types: priority (high, normal, low), project completeness (done, half-done, planned), project status (approved, rejected, pending) and type of information (work, important, temp, private). Marked files catch the eye and let you see the kind of information they contain before you read their names or open them.
