Hey everyone! 👋 I just launched Chrome Appearance Switcher on Product Hunt today, and I wanted to share the project with you all. The Problem it Solves: If you’ve ever tried toggling Chrome’s appearance, you probably noticed the Manifest V3 limitation: extensions can darken webpage contents, but none of them can change Chrome's actual browser frame (the tab strip, omnibox address bar, and toolbar) due to sandbox isolation. You usually have to dig into `chrome://settings/appearance` every time. How it Works: When Chrome is set to "Device" appearance, it mirrors Windows OS theme signals. The extension uses Chrome's official Native Messaging API to dispatch `WM_SETTINGCHANGE` notifications in Windows. Chrome receives the event and repaints its active window frame instantly — zero browser restart needed. Includes a global keyboard shortcut (Alt + Shift + D) to toggle anytime from any tab. The project is 100% free, MIT open-source, and collects zero telemetry or analytics. 🚀 Check it out and share your feedback: * Product Hunt Launch: https://www.producthunt.com/posts/chrome-appearance-switcher * Chrome Web Store: https://chromewebstore.google.com/detail/chrome-appearance-switche/giipkopljmnjmlkecknneemdkobcapnk * GitHub Repository: https://github.com/tljafar/chrome-appearance-switcher If you find this useful, I would really appreciate your feedback, questions, and support on Product Hunt today! 😻   submitted by   /u/Desperate-Charge2302 [link]   [comments]
