New: Highlight Updates ✨ — toggle the sparkle button in the Components toolbar and watch components flash on the page as they re-render. Instantly spot wasted renders: unoptimized components flash on every parent update, while ShouldRender-optimized ones stay dark. Outline-style flashes (React DevTools style) keep nested components readable.

▎ Also: the element picker and highlighter now share one DOM-mapping engine under the hood.

New: Element Picker 🎯 — click the ⊙ button, hover your app, and watch component boundaries light up with live names; click to jump to the component in the tree. Works on disabled controls and static content too. Plus: component parameter values now update live in the Details pane (with NuGet 1.0.0-beta.7), and the panel handles extension reloads gracefully.
