Currency Switcher needed

Hey currently we dont have option to allow switch currency for the users we need it specailly we who are living out side USA. As i can see its most demanding feature too becuse multple people asking to you for this feature here and codecanyon website too. By more advance mean if the people choose INR as payment gateway then it need to display only INR payment getways which we (admin) can decide from backend. And if the people choose USD then it must show only USA payment gatway like paypal To make this thing clear I am uploading some pics from Wordpress plugin and also sending its refer link too. Maybe this will be helpful for you to improve this currency switch function reference plugin link https://codecanyon.net/item/woocommerce-multi-currency/20948446 Please check screenshot also
