Take control of your media with Heero, a sleek, compact side panel designed to enhance your viewing experience across the web, enhancing images and videos in HTML5 players, including YouTube. ‎‎ ‎‎ 🎨 Real-Time Enhancement Fine-tune videos and images with brightness, contrast, saturation and sharpness adjustments. ‎‎ ‎‎ 🔍 Precision Viewing Tools Magnifier: Zoom into specific details without losing context. Rotation Control: Instantly fix awkwardly filmed content with a dedicated slider. Playback speed: from frame-to-frame to 16x faster playback. ‎‎ ‎‎ 🔊 Volume Booster Push your audio beyond the limit with a built-in gain controller for improved listening. ‎‎ ‎‎ ⚡ YouTube Supercharged Shorts: Watch Shorts in the standard, fully-featured video player. High-quality: Heero automatically sets videos to the maximum available quality for you. YouTube UI: Toggle the native UI off completely. HQ Thumbnails: Instantly open the high-resolution thumbnail of the video you're currently watching. ‎‎ ‎‎ 🛠️ Useful Tools Presets: Allows you to save your favorite enhancements and access them easily later. Screenshots: Take source quality screenshots in one click. Arrow Navigation Everywhere: Lets you use your keyboard arrows to skip or go back 5 seconds even in players without native support. Whiteboard: Draw directly over the screen to highlight or annotate content in real-time. Force Cinema Mode: Strip away distractions for a focused, immersive viewing experience. Video Downloader: Save your favorite videos from supported websites, now improved (YouTube not supported). Video Recorder: When download is not supported, allows you to seamlessly record videos in source-quality. ‎‎ ‎‎ ⚙️ Tailored to Your Workflow Customise how Heero behaves: set the panel to open automatically, restrict it to YouTube, or use Manual Mode to activate the extension only when specifically requested.
