Organizing notes, Tinderbox?

Can I quickly butt in and ask you about Nisus and Mellel. I own Mellel and did one project with it which went ok. Bookends live ref list was nice to have but the rest was nit mega smooth. How is Nisus pro behaving in comparison? Is it worth to shell out for it? All of
My colleagues use Word and track changes. (As a note, I own Word but don’t like it.) Nisus claims thezy are compatible with tracking changes. Is it worth for just simple 10-12 page research papers to buy it? Or should I just get more proficient at Mellel / suck it up and cope with Word?

As to the original wuestion: DTPO is brilliant. I am well underutlilizing it but would not want to be without. Bookends is a must as well for research. Very powerful. 10€ is worth it for wifi sync/year.

Cheers,

J.
