It would be highly beneficial to incorporate a drag-and-drop functionality for rearranging elements within a layer while building a page. This feature is essential and is already offered by various online builders such as Elementor, which I have previously used. Although this builder performs well given its current capabilities, there is a need to enhance some fundamental functionalities. Implementing this feature would significantly improve the user experience.

Additionally, the ability to group elements and move them collectively poses a considerable challenge in the current builder. This is also a basic requirement when designing a webpage, yet the available functionality remains quite limited. Therefore, I believe these two features are crucial to strengthening the overall effectiveness of this page builder.
