Hi,
There is no notification on order creation BUT there is a notification when orders are confirmed (there is an option in the config to specify an email address for that). We though that it would be more important for users to know when an order is confirmed than when an order is created. Isn't that ok for your client ?
Also you can easily create a plugin to send an email when an order is created:
www.hikashop.com/support/documentation/62.html#common
You can create a standard joomla plugin (take example on the history plugin we provide) and implement the function onAfterOrderCreate where you can send your email.
Features will be a must have for some and useless to others. Some users don't understand why there isn't an import feature where it should be standard, some will think about options, or ACL, or USPS shipping plugin, etc. We would love to have all the features our users want already in HikaShop. But we have a limited time to develop them. HikaShop is still young, it will come...
