Now that we have Categories [back] it would be very helpful if there was a SmartList criteria type of "Category" with the qualifier of "is/is not" and then a drop-down selection list of the current Categories.
No need Dan. The more directions we attack from the better the chance of victory. ;) I do like your idea of the drop down, populated with all existing categories. I'd also like to see categories in the Detailed Data List.
