Ever had annoying pages where the content width was limited, and the very packed table is squeezed into a itty bitty column making it impossible to navigate? No more!

• Click the extension button to toggle picker mode on the active tab.
• Hovering shows a highlight box and a compact element label.
• While picker mode is active, scroll down to move the selection to its parent element and scroll up to drill back down toward the originally hovered element.
• Clicking an element opens a new tab that renders only the picked element and its descendants, using the page's own stylesheets.
• Press Escape to cancel picker mode.
