Ok, Gordon posted this about 3 weeks ago – so I’m a little behind. Very cool, though – he’s using the ability of NewsGator to map custom RSS extensions to columns in Outlook:
NewsGator can render custom columns. This allows you to sort a folder by your custom field; price, in this case.
In order to support this, you can download and import custom field mappings. In the Options dialog, on the Rendering pane. Press the “Column Mappings” button, then “Import”, and select the field mappings file you downloaded.
