(http://www.tranglos.com/free/keynote_main.html Personally I've used "My
Notes Keeper" for a long time, but in recent versions, RightNote seems to catch up and I
think about switching. I'd like to hear your experience with these and similar
alternatives to KeyNote.

As a longtime user of KeyNote I jumped on RightNote when it became available. Unfortunately, while there was a period of time where the author provided frequent updates (to address minor issues), there hasn't been a significant functional update since my initial purchase. The added functionality over KeyNote does not outweigh the missing customization options like using my own custom icons for tree nodes and tabs, and lack of export options.

I ended up going back to KeyNote NF. Hopefully RightNote's author will actively enhance it.
