# Dashboard

## One-Liner
**The Dashboard provides an at-a-glance overview of your project's workflow status, statistics, and recent activity through an intuitive widget-based interface.**

## Pain Points Solved

| Pain Point | Current State | Dashboard Solution |
|------------|---------------|-------------------|
| **No project visibility** | Can't see overall project health | Project info banner with tech stack and development index |
| **Scattered metrics** | Stats across multiple locations | Centralized statistics with sparklines |
| **Unknown workflow status** | Hard to track session progress | Pie chart with status breakdown |
| **Lost in recent work** | No quick access to active sessions | Session carousel with task details |
| **Indexing status unclear** | Don't know if code is indexed | Real-time index status indicator |
