Just want to say how pleased I am to see and use Keynote-NF. Very glad that the programmer kept right to the Keynote style. Earlier I never found a satisfactory replacement for Keynote, free or paid, and stopped using it more for psyche reasons (no ongoing development) than any problems.
I did not stretch the features though, so I cannot give templates or fancy uses. Keynote and now Keynote-NF for me just has been an excellent quick and solid all-purpose note repository, combining hierarchy with fast free-form searching.
