TreeDBNotes

TreeDBNotes is a comprehensive note manager that allows you to create and organize your notes and thoughts.

It is a tree-like structure to easily recognize them and to find them when in need. The program offers lots of formatting options to create great-looking notes like if they were made in a professional text editor. You will be able to customize font, color, add bullets, customize paragraph features, and justification, to name but a few. You can also mark the name of the notes with different colors to recognize them more easily in the tree.
You can password protect sensitive data contained in folders or trees, use pre-made templates, and print your notes. Your notes can contain tables, hyperlinks, pictures, symbols, bookmarks, among many other things. Sadly, unlike the pro version, this one lacks alarms and reminders, which is a shame. The program comes with a demonstrative file which shows all the things you can do with the program, but if you still have doubts, you can consult the comprehensive help file which explains the different options in detail.
To sum up, TreeDBNotes is a professional note manager which offers advanced capabilities to create great-looking notes.
