Form + Document Debugging Mode (Advanced)

Add a debugging panel when editing or importing forms/documents. This advanced mode would show real-time schema validation, highlight missing or invalid keys, and let users test submissions without publishing the form. Key functions: • real-time validation • syntax highlighting • “simulate submit” for testing logic • warnings for mis-ordered blocks • auto-format JSON for readability This mode greatly improves developer workflows and supports power users building large-scale automation.
