I am having troubles in working with the frontend, especially making configuration in Products.
The reason is that I want to check how my settings are displayed in the frontend from the backend. It means that I do not need to save all configuration before I can see the product frontend page. I expect to check the frontend right in the backend.
Is there any way to make it real?
There are a lot of ways to help you to solve this problem
For example, you can install Admin Product Preview Plus Extension for your site to see the frontend page right from the backend. Moreover, this extension also supports more other functions related to preview function in the admin
Thus, with the help of this extension, you can absolutely check how your settings are displayed in the frontend from the admin while you are making configuration.
There is the application called Store Manager for Magento and it has got the option to view product page (front-end) directly from the product (right-click on products -> view Product Page) -
You can download 14-day fully-functional version of the application and test how it works - check the link in my signature.
