Just a few requests regarding filtering tickets:

I'd like to see the option to filter using is/isn't statements. For example, I could filter out tickets that are a specific topic, but leave all the rest.

Also, I'd love to be able to see a "none" for filters. Similar to how there's an "any" option. That way I could find any uncategorized tickets and categorize them. I'm a type A in that way. :)

Thanks!

Agreed, the isn't (or not) concept would be very helpful in the Category field.

And a "none" option is also very helpful for finding tickets where a non-required field is missing, but you want to know that.
