Bring Bitstream Font Navigator Back to WordPerfect Office

WordPerfect used to come with Bitstream Font Navigator, but now it appears only to be included with CorelDraw. WordPerfect users need font management, too. I don't get why BFN isn't available as an add-on to WPO, similar to the Oxford Concise Dictionary add-on. I'm getting by the BFN 4.0 from several versions of WordPerfect ago, but would like to have access to the latest version.
