### What we like

Analyzes mouse movements and tracks keyboard navigation to predict user element interactions. Allows triggering prefetching based on intent, rather than simple viewport status. Makes UIs feel more responsive and reduces unnecessary fetches. Integrates with Next.js and React Router. Includes a debugger tool.

### Tradeoffs

Next.js only prefetches in production, so it can be difficult to debug behavior locally.
