Thanks -- I'd searched for "Important" not "Importance" in the "Other 
..." list, and so hadn't found it. It's not clear what it means, and a 
few simple tests with it haven't done anything noticeable.

I suspect the tag/flag is available outside GMail somehow, because I've 
tried a third-party Mac OSX mail client that knew the tag/flag. It's the 
recently-launched AirMail, and in the preferences it maps 
"[Gmail]/Important" to this internal special flag/tag.

Trying to add a Condition where Tag includes "Gmail/Important" or 
"Important" don't work either. And I can't test for "[Gmail]/Important" 
as I can't define an IMAP term with angle brackets in the tags dialog. 
(Well, it allows '[' but not ']' oddly enough. Bug?)

Thanks,
