With the Download Them All plugin, how can you delete an entry in “Fast Filtering”? I see how you can delete regular custom filters created in Preferences, but there doesn’t seem to be a way to delete those created in Fast Filtering, which is a problem, as they all seem to be applied, unless you check “Disable other filters,” but I need more than one filter.

The add-on page has contact information you can use to ask this question.
