Summary

Styling options are limited, and there’s no direct way to fully customize individual components. Request:

• Add CSS ID and CSS class fields to every element
• Provide a dedicated Custom CSS panel per element
• Allow global and per-page CSS overrides

Why should this be worked on?

This level of styling freedom would enable advanced customization of appearance, animations, and behavior, similar to modern UI builders that offer near-pixel-perfect control.
