User environment settings must have a name and can optionally have a label and a tag.
As the name is used for the Run once logic, changing the name of an existing setting may cause the setting to apply once again. The label and tag fields can be used to describe or organize the settings. The Group By Tag ribbon button uses this tag field for grouping the list items. When editing a user environment setting, the Previous and Next buttons can be used to open the previous or next setting for editing, based on the current sort order of the list.
