- **Agent Identification**: Color-coded agent badges with initials
- **Keyboard Navigation**: Intuitive keyboard shortcuts
- **Connection Status**: Real-time connection monitoring
- **Auto-update Toggle**: Control automatic timeline refreshing
- **Terminal Optimized**: Responsive layout for various terminal sizes
## Installation
From the project root:
```bash
pnpm install
pnpm build:shared # Build shared dependencies
pnpm --filter agent-timeline-tui build
```
## Usage
### Development Mode
```bash
pnpm dev:tui
