I know that when a lead is converted to an opportunity a dialog asks whether you want to create a customer (in res.partner) at the same time.

For my application I don't want to use leads. Any potential customer goes straight into the opportunities pipeline. Although I still want a simple way of converting that opportunity to a customer.

I could probably go ahead and customize this into my application but I would like to know if anyone knows any apps/extensions or quick solutions available.
