2.1. Some FAQs about Unsen EComposer
I have theme of The4 installed and full features, why do I need theme for EComposer? Theme's The4 is of great quality, however EComposer was not developed to replace Theme's The4.

When should I use Theme's The4 EComposer? When you have a high need to build landing pages or about, contact... at your discretion. You can absolutely use EComposer to create those pages.
I just want to use Theme's The4 is that possible? Absolutely, if your need is everything Theme's The4 has then just use it. Theme's The4 EComposer is only recommended when you have high customization needs, and want more advanced functions (like upsell extensions and high-quality layouts...). To use Theme's The4 EComposer, you are still required to installTheme's The4.
What is EComposer better than Shopify editor? It's pretty hard to explain it all here, you can try the demo at https://demo.ecomposer.app. Some outstanding powerful features can be mentioned such as a diverse library of libraries (you can combine them with Theme's The4), an extension store that allows you to have advanced features, a flexible drag-and-drop system, Various elements that allow you to build anything, the auto-save function allows you to avoid losing your work, easy to use custom fonts.....
