Need some help to edit

First of all, great plugin.

I want to edit some things,

1. Ist possible to change order in the payment page and remove thing like,
i want to remove ‘Thank you. Your order has been received.’

and first on the top to have Order details and the Order instructions like btc amount and address.

And ist possible in the future to add a https://chain.so/ link with a direct link to the btc address so people can follow the payment ?

2. I want to edit the mail that are sent to the costumer, right now its sent in english,

‘Hi ,
An order has been created for you on comapnyname. Your invoice is below, with a link to make payment when you’re ready’

i want to translate that text and add/remove some of it, can that be done ?
