When you add a Checkbox field to a table, you can choose a style graphic used when the box is checked. You can choose from many graphics like a Check, an X, a Star, a Heart, etc.
When you add a Function field to a table that returns numbers, you have the option to format the numbers. However, If the function returns a Boolean, the field will display a 1 or 0. (I know you can add code to the function to display graphics, but that shouldn’t be necessary.)
It would be nice to see a checkbox-style format for Boolean values returned from Function fields. Having the option would make the UI consistent when displaying Boolean values and performing calculations on these fields.
