• Custom Tags - Configure custom HTML tags to highlight
• Keyboard Shortcut - Toggle highlighting with Ctrl+Shift+H (Cmd+Shift+H on Mac)
• Non-Intrusive - Overlays don't interfere with page interactions
• Smart Positioning - Overlays follow elements during scroll and hide when out of view

• State Persistence - Remembers your settings across browser sessions
