Photos with that tag assigned will be displayed in the Library.
Preset tags are typically action-based to aid workflow, i.e. Reviewed,
To Fix, To Print, and To Share.
Not tagged status
The Not tagged tag will let you view photos that have no tags assigned.
This can be used to separate your "processed" photos from
"unprocessed" photos—newly imported photos will often not have
assigned tags. As you process your photos you can use the Not tagged
tag to check your progress.
Quick tags
You can filter by Quick tags in an identical way to Descriptive tags by
selecting either Not flagged, Flagged, Not rejected, Rejected, or any
combination of these.
