Just a quick note to say that I've just pushed version 1.3.1 out to wordpress.org.
The latest version contains support for including custom checkout fields in the CSV export after some kind sponsorship for the feature.
On the TODO list are:
* Stock information / Low stock / Out of Stock alerting widget
* Support for variations in the CSV export
* Support for Coupon Codes in the CSV export
* Support for shipping in the CSV export
Any other ideas welcome ...
