Payment of orders not paid immediately

Just tried out this feature.
Could customer also change their method of payment at this point?

It's not possible at the moment but we'll add that to the todo list.

Thanks, but just noticed something else.

If in the admin screen I change the payment method to Pay On Delivery when the customer goes into the 'My Orders' screen the button shows as 'Pay with Collectionondelivery' - payment method shown as all one word.

Looks like the text is coming from the plug-ins element name (element column of extensions table).

As its in the order listing template I can change the code for this, but it would be better if the default behavour displayed something like 'Pay with "Collection on Delivery"'.

Where Collection on Delivery comes from the name field on the payment method configuration page.

Indeed. The problem is that there is no function at the moment to retrieve the name of a specific payment method. Using a payment selection dropdown and a "Pay" button will be the solution I think. That will add a feature and fix that problem at the same time.
