Adequate
I paid $65 for a past version that had far more options and capabilities. However, that version does not work under Yosemite and El Capitan. In comparison, this version is very limited and disappointing.
Still, it is speciality software. I use it once or twice a year to produce timelines. When I need it, I need it, and this version, though limited, works. The best I can say is that it is adequate.
