[IxDA Discuss] select exact number widget?

[Mark Schraad]

Like I said - it is not elegant, but it does give the user an  
indication of the limit (we also message this proactively) and the  
ability to correct it. Unfortunately we do not have the luxury of a  
rich graphic environment or long development cycle. As we do  
iterative updates this is one of the first issues to be reviewed and  
upgraded.
