I have MANY filter rules...100+? And sometimes the incoming email changes patterns, and I'd prefer to alter the old not-quite-good rule, rather than just adding another rule. But it seems that the only way to find the older rules is to scroll through the list and hope that I named the old rule efficiently. So: feature request: a 'search' of filter rules, to find rules that match a particular filter name or filter pattern. Maybe such a capability exists, and is just well hidden!
Currently, you can only search by name, by selecting a row in the list and typing some characters. You'll see a type-ahead box with your characters in, and the first row matching those chars will be selected.
