Domains - allow add a button to allow only unique values to be shown in field calculator and symbology.
Do you mean that you only want to see the domain values that actually exist as attributes in your table and not the entire list of possible/unused domain values? If so, I agree. It should be a checkbox at the top of the symbology category list ("Only include current values" or something).
As an example, the screenshot below is of an exported subset of our Arborist data collection template. This exported feature class has only two features, but if I symbolize on the Species field, which has hundreds of domain values, it tries to create classes based on the entire domain list, not the values in the Species field for the two features in the feature class. It would be very helpful if we could opt to symbolize on current unique values in the table OR on domain values (since sometimes we want our symbology to include all possibilities because features are still being added).
For the field calculator, it already exists. Just choose from the Current Values section at the top of the Insert Values list.
