# Task List and Filtering Interface Implementation

## Overview
Enhanced task list interface with advanced filtering, status updates, deadline visualization, and task assignment capabilities.

## Features Implemented

### 1. Enhanced Filtering
- **Search**: Full-text search across task names, project names, shot names, and asset names
- **Status Filter**: Filter by task status (Not Started, In Progress, Submitted, Approved, Retake)
- **Task Type Filter**: Filter by task type (Layout, Animation, Simulation, Lighting, Compositing, Modeling, Surfacing, Rigging)
- **Department Filter**: (Coordinators/Admins only) Filter tasks by department role
- **Sort Options**: Sort by deadline, status, name, or last updated

### 2. Task Status Updates with Dropdown
- **Inline Status Updates**: Click on status badge to open dropdown selector
- **Visual Status Indicators**: Color-coded status badges with consistent width (130px)
- **Status Options**:
  - Not Started (Gray)
  - In Progress (Blue)
  - Submitted (Purple)
  - Approved (Green)
  - Retake (Red)
- **Immediate Updates**: Status changes are saved immediately to backend
- **Toast Notifications**: Success/error feedback for status updates

### 3. Deadline Visualization with Urgency Indicators
- **Color-Coded Deadlines**:
  - **Overdue**: Red background with alert icon
  - **Urgent (≤3 days)**: Orange background with clock icon
  - **Warning (≤7 days)**: Yellow background
  - **Normal**: Default styling
  - **Approved**: Muted styling (deadline no longer critical)

- **Enhanced Date Display**:
  - Shows relative time (e.g., "2d overdue", "Tomorrow", "3d")
  - Includes visual icons for overdue and urgent tasks
  - Background highlighting for urgency levels

### 4. Task Assignment Interface
- **Assignment Dialog**: Modal dialog for assigning tasks to team members
- **Department Role Filtering**: Filter available users by department role
- **Visual Department Badges**: Shows each user's department specialization
- **Smart Assignment**: Only shows project members who can be assigned
- **Coordinator/Admin Only**: Assignment feature restricted to appropriate roles

### 5. User Experience Improvements
- **Clear Filters Button**: Quick reset of all filters
- **Responsive Layout**: Filters wrap appropriately on smaller screens
- **Loading States**: Visual feedback during async operations
- **Error Handling**: Comprehensive error messages with toast notifications
- **Click-to-View**: Click anywhere on row to view task details
- **Stop Propagation**: Status and assignment actions don't trigger row click
