Notes provide a mechanism for writhing, capturing, aggregating and editing content. Notes can be created from scratch and inserted anywhere in your tree. They enable you to capture parts of information elements rather than their entire content by dragging pieces from the source to a note. This also enables you to divide the contents of an item, such as a web page, into multiple components that you can then place at different locations in your tree. With this approach you can separate ideas and place them in your tree where they make most sense to you. With notes you can:
Drag images and content into a note from web pages and other documents.
Have a powerful set of editing and formatting tools.
Can spell check.
Use a ruler and tab stops
Insert tables and hyperlinks.
Attach files.
