Export/Import Invoices

Hi. First off I would like to thank you for this useful plugin.

I was interested to read on your blog that the new update of wp-invoice had added the ability to export invoices. I was wondering where I would find this because even though I have updated the plugin I cannot find where to do this within the plugin. Love to know how to export as it will be a valuable asset.

Thanks for your time.
