View product button on the product edit page in Magento admin

Hello dear friends. While working with Magento, many of you may have noticed that, when you manage products in the admin you need to see how the product looks on the frontend. Of course, you can open a new page, then open frontend search or write direct url address to this product page, as Magento does not have the button or direct link from the admin page to the frontend product page, but it is not very simple way. Let’s create module with this feature.
