The bulk export to XML is a very handy feature.
Another very handy feature would be have a bulk export of the snippets into a single file, but with non of the XML markup. Make the output 'usable' PHP that could be cut and paste directly from the output file and used again, without having to remove the snippet, code, name, description markup.
This would allow for quick and easy recycling of each snippet, in the event the user was not using the Code Snippets plugin on the next site.
Thanks for the plugin, it is proving very handy!
