Nightify - Beautiful Dark Mode

😣 The Problem

The web is built bright. White backgrounds everywhere, harsh contrasts, blinding screens at 11pm. Your eyes pay the price. Most dark mode tools are either too aggressive — breaking layouts, hiding videos, turning pages completely black — or too basic to be useful. Nightify gets it right.

⚡ What It Does

The moment you install Nightify, every website gets a smooth, intelligently applied dark theme. Not a crude color overlay — a real theme that respects the page's layout, keeps your videos visible, and never breaks what you're looking at.

You get a clean popup panel with three tabs: 🎨 Controls, 📦 Presets, and 🌐 Sites.

🎨 In Controls, you can dial in exactly how dark, warm, blue-light-filtered, contrasty, saturated, or sharp you want your screen. Seven sliders let you go further: Brightness, Contrast, Blue Light, Sepia, Grayscale, Saturation, and Sharpness.

📦 In Presets, you choose from eight one-click configurations — 🌙 Default, 🔥 Night Owl, 💼 Office, 📖 Reading, 🎬 Cinema, 🌇 Sunset, 🖤 Monochrome, ✨ Vibrant — covering most situations instantly. Export and import your settings as a JSON file to backup or share your perfect configuration.

🌐 In Sites, you exclude any website where you want the original look preserved. One toggle disables Nightify entirely on the current page. The whitelist keeps your exceptions saved forever.
