TL/DR: remove all other values on by default in symbology>unique values
Currently in ArcPro 3.6.2, Whenever I select Symbology>Unique Values, "All other values" is turned on by default. This means that <all other values> shows up immediately and must manually be deactivated, every time. This is a waste of time because, especially initially there will be no other values until the user removes value classes. Ideally, all other values would only show up when count for all other values<0 or if the user manually turns it on via the "more" drop down. While this is minor improvement, it would save 3-5 seconds each time someone engages with a feature layer with unique values.
