🔹 Instant wireframes – turn any site (or a blank canvas) into a playground for mockups
🔹 True WYSIWYG – change button labels, headers and colours right on the screen
🔹 Keyboard friendly – Ctrl/⌘ + C/V to duplicate, Delete to remove, Esc to cancel
🔹 Pixel-perfect exports – save the selected area as PNG or copy a screenshot to clipboard
🔹 Privacy first – no network calls, analytics or trackers; data lives in chrome.storage.local
🔹 Lightweight – injected only on demand, keeping everyday browsing fast
