 - **See what your agent means.** An architecture it's proposing, a flow it's
   tracing, a UI it's about to build — shown, not described in a paragraph you
   have to picture in your head.
+- **Multimodal.** Combine diffs with mermaid diagrams, terminal output with HTML
+  explainers, and more. Combine surfaces to illustrate ideas better.
 - **Faster, and fewer tokens.** sideshow surfaces are optimized for LLMs, so the
   agent produces higher-fidelity diagrams and visualizations faster and using
   fewer tokens.
