this outliner/note taking tool looks similar to KeyNote or TreePad, but is open source and still under development, not like KeyNote which have been abandoned.
the author has put a blog and forum where u can post suggestions about his program
website is: http://www.neomem.org
i asked him to make this program storing its settings in the *.ini file instead of registry, as stands for now in 1.1c and he promised to do it in the next version maybe within a week
