# UI/UX Improvements Summary

## Overview
Comprehensive UI/UX enhancements to the marketing app focusing on user feedback, loading states, empty states, micro-interactions, and accessibility.

## 1. Toast Notification System ✅

### Components Created

### Integration
- Wrapped app in `<ToastProvider>` in `App.jsx`
- Added toast notifications for:

  - Attachment operations
  - Error states

### Usage Example
```jsx
import { useToast } from '../components/ToastContainer'
