What should Markdown-native UI be useful for first?

We’re launching XCON Viewer to explore a simple idea:

Markdown is great for writing specs, docs, product notes, and technical explanations — but it is still limited when you want to describe an actual interface.

With XCON Viewer, we’re trying to make it possible to write structured UI blocks inside Markdown and preview them visually. Things like cards, charts, grids, dashboards, reports, and screen concepts can live directly next to the text that explains them.

The part we’re thinking about most is where this should be useful first.

A few possible directions:

• Product specs with visual UI examples

• Technical docs with interactive-looking components

• Data reports with charts, grids, and dashboard blocks

• AI-generated UI review before turning ideas into code

• Lightweight prototyping for makers and small teams

Curious to hear from the PH community:

Where would you actually use UI inside Markdown?
