Suggestion: put an 'only' button next to each filter checkbox.
Reason: The most common query, at least for me, is to check only "Unreported". It's a pain to uncheck 5 boxes every time I want to do that.
Just wanted to add my two cents that the filters around reports could really use a re-vamping with additional functionality and report statuses as a whole.
You can filter for 'only' certain statuses now by mousing over the filter button and clicking the magnifying glass!
