When inserting an expression into an Advanced Search, show the current available values in the field, as Classic currently does. When I insert an expression into an Advanced Search, I don't have any way to see what the current values in the field are. Sometimes I even already need to know the ID of value in the table. In Classic, that information is presented as to me, and I can pick from the list instead of having to enter it from scratch or knowing the table record ID.
