Now you can print the primary sequence with only problems or with everything else. In addition you can easily print the problems from the whole course (or from part of the course). To print problems from the part of the course we added additional menu (thanks Jeremy). But the navmap menu for item #3 (the same as for item #2 - see previous submission) contains more information than we really need and has to be changed.
