The Struggle

Device toggling, broken layouts, endless downloads – you know the drill

Responsive Testing

🔁 Open devtools

📱 Toggle device modes one by one

↔ Scroll & click separately

😩 Repeat for each screen and device size

Live Edits

🔍 Inspect in devtools

🧩 Dig into HTML/CSS

🎯 Guess at what to change

💥 Hope it doesn’t break layout

Visual Overlays

🧱 No built-in way to view layout structure

❌ Can’t see padding, margins, or grids at a glance

🧩 Manually add borders or use clunky third-party tools

🫣 Design structure stays hidden and hard to debug

Asset Extraction

📸 Open devtools or use screenshot extension

🧰 Use separate tools for images/SVGs/fonts

📂 Manually download one by one

Tracking Changes

🧠 No memory of what you just edited

📄 Can’t track replaced styles or assets

🔄 Constant re-checks to see what’s been tested already
