A note is an element of a Tinderbox file, it has a title, a text body, and attributes; the title and text are themselves attributes of the note ($Name and $Text). A note is best thought of as the 'atomic' entity of information within a Tinderbox file.
Notes are the basic units of writing and information in Tinderbox document. There is no fixed limit to the number of notes a Tinderbox document can handle; it can easily manage thousands, even tens of thousands of notes. At some point performance will become a limiting factor, but use of agents and rules is a bigger factor in performance than the sheer number of notes.
A note may also act as a prototype for other notes.
A note is edited via the text pane, the right side of the default window layout. The text pane displays information about the currently selected note.
Any note containing other notes is also regarded as a 'container'; put another way, a container is any note that has children.
Agents are a special class of container, as they create/control the aliases within themselves. agents may not contain other notes, with the exception of adding adornments in map view
