It amazes me, even now this far advanced in development, that ArcPro still does not offer a simple 1-click grab of unique values to clipboard option. I often need to report what the values are in say a categorical field. I would love ArcPro to offer up a 1-click option that simply copies the unique values to clipboard so I can paste them into a word report or text file, or dare I say it metadata!
ArcPro offers a variety of places where it must have calculated the unique values which could conveniently be copied into clipboard. The obvious place is the symbology pane, why not have an option in the More menu to copy values to clipboard. The interface does not change because it just becomes another option in the little menu.

Another obvious place, and it blows my mind its not there, is in Data engineering!

You could right click on unique and have it copied, seems very obvious to me...
YES I know Summary statistics Tool essential creates that list of values but one is forced to run a geoprocessing tool, to create a dataset (even if it is in-memory). So many hoops to jump through when its clearly obvious that UI has already created that list and it is simply not exposed.
In the application options one should be able to choose if the separator between values is a tab/return/semi-colon or other character.
