Hello,
Thank you for showing interest in our plugin. Following are answers to your questions:
Yes, once you purchase the plugin, you will get live person support for a complete year from the date of purchase.
Yes, it supports Euros. You can select currency as per your requirement.
Can you explain in detail, what exactly you want to accomplish here?
Yes, empty fields are hidden not only on the single page but on all plugins pages.
You can change the structure of pages by overwriting template files just like woocommerce. But if you are using any Page Builder plugin and you want the plugin page content to appear in the middle of other elements than you can do so by just inserting plugin shortcode at specific location.
No, the plugin does not have an option to import data from CSV file. You can import data only from JSON file.
Hope that helps. Thank you.
