Can I indent the first system of a piece, the way its done in expensive printed music?
Yes. ‘Page Setup | Options | Staff labels | First system’ puts a label in front of each staff for the first system of a piece. These labels are the titles you can give to staves under ‘Staff | Staff Properties | General | Name’. If you would like to indent the first system without placing labels, simply name the staves using the character Alt+0160. (This is the non-breaking space character in Times New Roman, NWC’s default font for printing this information).
