 Stylizing a layer using unique value classification is very useful.
 However, if the underling data in the classification field is modified
 after classifying in QGIS, then new classifications are not displayed.
 This omission can often be critical to the end user.

 Most GIS software have a ''default'' style for unique classifications.
 This is analogous to the ''default'' or ''else'' part of a case or switch
 programming statement. It would be very useful in the Symbology tab of
 Layer Properties to have a checkbox for inclusion of a default style, and
 the ability to modify the style (as with the other classifications).
