How a customer could cancel a "Created" command ?

I have many customers creating commands (probably on smartphones) that don't go through the paypal payment process.
Then, their commands stays created and some time after, they re-create command(s), until they pay the last one.

My problem is with the previous created commands. Mainly the customers don't want to pay again and agree to cancel the orders.

I don't want (for administration charge reasons) to cancel myself the commands in the backend, after contact with customers.
I would like that they have the ability, in their Customer Panel to click on a "Delete order" button, like they have one to pay with a delay a created order.
I observed that on Paypal site, when you click on the "Cancel and go back to the site" link, the command is really cancelled in Hikashop.
It's a way, but not fine for customers.
Of course, the "Delete" button should only appear for "Created" orders, not for "Confirmed" ones.

Do you know a way to add a such "Delete" button ?
Thanks by advance.

Hi codewarrior,

A cancel button already exist, you can change the check of cancel button displaying.
Edit the file "order / listing" in HikaShop > Display > Views.
And change or remove the line:
By this way the customers will be able to cancel their orders.

You can just configure the option "Cancellable orders statuses" of the configuration and your users will be able to cancel their created orders. No code change needed

Thanks Nicolas, it works fine !
