DisplayExpression allows the use to customise the way a note's name is displayed within Tinderbox. it is one of several such display expressions.
Some users find it helpful to use actions and rules to append information to not names, e.g. a word count, number of children or the value of some attribute. However, this does change the actual name of the note and can cause problems with other actions which don't expect note names to change.
DisplayExpression helps overcome this by working in conjunction with another new (read-only) attribute, DisplayName. The latter (q.v.) display's the Name of a note after the action in DisplayExpression is applied. The existing Name value is unaffected allowing other notes to make explicit reference to a given note. See a further description.
