Keynote

Most occupations and activities require taking notes at one point. Some people prefer to stick paper notes on their monitor and desk, others choose to write everything neatly in a notebook, others yet pick another method of keeping notes and going through them later. KeyNote lets you explore and enjoy an efficient way of storing and accessing notes.
KeyNote is a note editor and organizer that lets you create and store text notes in an easy-to-use way. Unlike paper notes and text editors, this application lets you take the notes to the third dimention: you can assemble different notes within a single file, while each note can consist of several notes linked by a tree-like structure. Notes can contain not only formatted text, but images too.
The program gives one innumerable resources for formatting notes and has some other useful features like macros, templates, plugins, etc. Download this free tool today and check it out yourself.
