Some enhancement requests for the Query widget:
1. allow a blank value to be used in the query when Ask For Values is specified (the blank value should be flagged as an error at run-time, not when configuring the widget)
2. remove the requirement for the Hint when Ask For Values is specified. There is usually no need for a hint as the dialog is self-explanatory
3. make the "is greater than", "is less than" parameter a variable.
4. in fact, expanding on #1 and #3, most of the options on this dialog could be provided for the user to change at run-time. Eg, select the field, select < or >, input the value, hit Apply
Thanks,
Steve
