The NCrunch Metrics Window allows you to exclude certain metrics from visible aggregation. This setting controls whether the NCrunch engine stores the excluded metrics in the shared NCrunch project settings files, or in the user NCrunch project settings files.
When this setting is enabled, NCrunch will always save the list of excluded metrics in shared project settings files.
When this setting is disabled, NCrunch will always save the list of excluded metrics in user project settings files.
This gives a way to control whether excluded metrics should be kept locally or shared with your team.
