To solve this, I vibecoded <strong>OneUI QuickPanel Customizer</strong> in a collaborative pair-programming partnership with an AI coding assistant, built using <strong>React 19</strong>, <strong>Vite</strong>, and <strong>Tailwind CSS v4</strong>.</p> <h2> 🚀 Key Features </h2> <ul> <li> <strong>Visual Calibration</strong>: Upload a screenshot of your QuickPanel to auto-calibrate active panel regions.</li> <li> <strong>Built-in Image Editor</strong>: Crop, scale, align, and tweak blur &amp; opacity filters right inside the web app.</li> <li> <strong>Real-time Live Preview</strong>: View how your customized wallpaper blends with UI elements before downloading.</li> <li> <strong>Persistent Profiles</strong>: Save calibration profiles for your specific Galaxy model locally in your browser.</li> </ul> <h2> 🛠️ Stack &amp; Engineering </h2> <ul> <li> <strong>Frontend</strong>: React 19 + Vite 8</li> <li> <strong>Styling</strong>: Tailwind CSS v4</li> <li> <strong>Canvas Engine</strong>: HTML5 Canvas API for sub-pixel image cropping &amp; filters</li> <li> <strong>Workflow</strong>: Vibecoded with an AI coding assistant</li> </ul> <h2> 🔗 Try It Live &amp; Open Source </h2> <ul> <li>🌐 <strong>GitHub Repository</strong>: <a href="https://github.com/A-b-h-i-n-a-V-01/OneUI-QuickPanel-Customizer" rel="noopener noreferrer">github.com/A-b-h-i-n-a-V-01/OneUI-QuickPanel-Customizer</a> </li> </ul> <p>If you find this project helpful or want to contribute, stars ⭐ and feedback are greatly appreciated!</p> webdev react android opensource
