📝 Release Notes – v1.2 (Color Picker Enhancements)
Release Date: 2025-07-26

🎨 What's New

✨ Custom Color Picker Integration
Replaced native <input type="color"> with a fully integrated Pickr color picker.
This improves cross-browser compatibility (especially in Firefox, where native color inputs close the popup).

Highlight color picker now aligns perfectly with the label and theme selector
Fixed flexbox styling in the settings panel for clean, consistent spacing

🐞 Bug Fixes
Fixed issue where color picker was not showing due to CSP blocking external scripts
Resolved JavaScript errors when referencing a removed <input id="theme-color">
Fixed layout bug where theme dropdown and color picker were right-aligned

✅ Result
A much smoother and polished UX with inline color customization that works seamlessly across Chrome and Firefox.
