Clueless: DNS editor UI: feature request: import / export

In Clueless’s DNS editor you can download a zone file, but that's only part of the story. You don't see the corresponding PTR records. I would like to be able to import and export the entire state. It would be very nice if it were in some human readable format that could be edited with a text editor.

Multiple import/export formats would be nice. Suggest both import and export the complete state in CSV, say, for spreadsheets. Import/export in XML too would be a great as second alternative because then there could be a published schema and could use tools such as XSL.
