Organizer based on Qt Assistant 4.3 with build-in WYSIWYG HTML editor based on QTextBrowser with some code from Qt 4.3 demo "textedit". All of these had to be mostly rewritten to fit the needs of the project.
The project is in it's development stage right now, but it is pretty stable.
I use RA in my everyday work for all notes. So, you can give it a try!
The project is openned for new developers and contributors!
