Thank you very much for this fantastic module.
After clicking on the "Create and send a custom newsletter" link, if you choose to save and send a test newsletter, you can't edit the draft again nor send another test. All you can do is click on the "send" link.
Is this a bug or a "feature"?
Wouldn't it be nice to be able to edit the draft again and keep on sending tests untill satisfied with the results?
Thanks again for the hard work and keep it up!
