In the Inspector, under Data Formatting, Format: Boolean, "Show non-zeros as"... it has a 7-character limit. It would be cool if the limit was something more like 8 characters, or even 9... or 42, or 255. Sorry, I'm getting carried away.
Examples of things you might want to display non-zeros as:
Approved - 8 characters
Excellent - 9 characters
Report submitted - too many to count
Of course we can always place yet another text object on the layout and use the the "Hide object when" feature -- which I love! -- but it's so simple and elegant to use the field itself as a Boolean. However, the current character limit makes it often not an option.
