🎨 Major UX Overhaul - December 20, 2025

What Changed

This update transforms the Lighthouse Actor from "technical tool" to "anyone can use it" with zero documentation needed.

📋 INPUT: Before vs After

Before (Technical Jargon)

Title: "Lighthouse Audit Configuration"
Field: "Device Type"
Description: "Configure how the audit simulates real-world conditions"

After (Plain English)

Title: "🔦 Lighthouse Performance Auditor"
Field: "📱 Test Device"  
Description: "Mobile = 375px screen + slower network. Desktop = 1350px + faster network."
Option: "📱 Mobile (Recommended - 80% of users)"

Key Input Improvements

Every description is now in plain English
- Before: "Throttles network speed to 4G (1.6 Mbps) and CPU"
- After: "Tests realistic conditions (4G speed, slower CPU). Turn OFF only for internal testing."
Added context and recommendations
- "📱 Mobile (Recommended - 80% of users)" vs just "Mobile"
- "Interactive report you can download and share" vs "Saves the complete interactive Lighthouse HTML report"
Better section organization
- 📊 What to Test
- 🎯 Test Settings
- 📦 What You Get
- ⚙️ Advanced
Emojis for visual scanning
- Every field has an icon (⚡ ♿ ✨ 🔍 📱 💻 📸 💡 🔧)
- Makes it easy to scan and find what you need

💡 Why These Changes Matter

For Non-Technical Users

No documentation needed - Everything is explained inline
Know what to do - Clear recommendations and priorities
Understand results - Plain English, not technical jargon
Make decisions - Context for every option (why/when/trade-offs)

For Developers

Still get all the data - Technical details are in technicalDetails section
Structured better - Easier to parse programmatically
More context - Explanations help explain results to stakeholders
Raw data available - Can still get full JSON/HTML reports

For Apify Store

Self-service - Users don't need support to understand options
Better reviews - Users can actually use it without frustration
Clear value - Immediately see what you're getting
Professional - Polished UX shows attention to detail

🚀 What's Next

Rebuild in Apify Console to test the new UX:

Go to your Actor in Apify Console
Click "Build" (not Clean build)
Test with a sample URL
Check the dataset output - should be much clearer!

The Actor is now production-ready for Apify Store publication. No documentation needed - users can just start using it!
