## Pain Points Solved

| Pain Point | Current State | Terminal Dashboard Solution |
|------------|---------------|-----------------------------|
| **Scattered terminals** | Multiple terminal windows | Unified tmux-style grid layout |
| **No context linkage** | Can't associate terminal output with issues | Association highlight provider |
| **Panel overload** | Fixed layout wastes space | Floating panels (mutually exclusive) |
| **Missing tools** | Switch between apps | Integrated issues, queue, inspector, scheduler |
| **Limited workspace** | Can't see code and terminals together | Resizable three-column layout |

## Usage Examples

### Basic Terminal Dashboard

```tsx
import { TerminalDashboardPage } from '@/pages/TerminalDashboardPage'

// The terminal dashboard is automatically rendered at /terminal-dashboard
// No props needed - layout state managed internally
```

### Using FloatingPanel Component

```tsx
import { FloatingPanel } from '@/components/terminal-dashboard/FloatingPanel'
import { IssuePanel } from '@/components/terminal-dashboard/IssuePanel'

function CustomLayout() {
  const [isOpen, setIsOpen] = useState(false)

  return (
    <FloatingPanel
      isOpen={isOpen}
      onClose={() => setIsOpen(false)}
      title="Issues"
      side="left"
      width={700}
    >
      <IssuePanel />
    </FloatingPanel>
  )
}
```

### Panel Toggle Pattern

```tsx
import { useState, useCallback } from 'react'

function usePanelToggle() {
  const [activePanel, setActivePanel] = useState<string | null>(null)

  const togglePanel = useCallback((panelId: string) => {
    setActivePanel((prev) => (prev === panelId ? null : panelId))
  }, [])

  const closePanel = useCallback(() => {
    setActivePanel(null)
  }, [])

  return { activePanel, togglePanel, closePanel }
}
```
