LightBar For Keyboard v1.0.2

Energy Efficiency vs. Hardware Lighting

Why use software to light your keyboard instead of a physical illuminated keyboard or a USB lamp? The answer is energy efficiency and convenience.

Hardware Consumption (Illuminated Keyboard / USB Lamp):
A standard USB port supplies 5 V. Depending on the number and intensity of the LEDs, a physical light consumes constant extra power:

• Minimum (small USB lamp): 5 V * 0,1 A = 0,5 W
• Maximum (RGB keyboard / bright lamp): 5 V * 0,5 A = 2,5 W

LightBar Software Consumption:
Our application leverages the screen you are already using.

• LCD Monitors (IPS, TN, VA): The backlight is already on. Displaying a white or colored bar merely twists the liquid crystals to let existing light through. Extra power required: 0 W.
• OLED Monitors: Each pixel generates its own light. While a full white bar uses about 2,0 W, we introduced pure color profiles to bypass subpixel activation and save battery:
  • Pure Green: ~0,5 W (75% savings)
  • Pure Red: ~0,3 W (85% savings)
  • Yellow: ~0,8 W (60% savings)

LightBar for Keyboard - Initial Release - v1.0.0

🚀 LightBar For Keyboard v1.0.0
This is the first official release of LightBar For Keyboard. I created this tool to provide a discrete, controllable light source directly from your monitor, perfect for typing in low-light environments.

🌟 Key Features
Docked Mode (Default): Native Windows AppBar integration. The bar automatically reserves space at the bottom of your screen, pushing maximized windows (like Chrome or VS Code) upward so they never overlap your light source.

Floating Mode: Total flexibility! Switch to Floating Mode to freely drag the bar anywhere on your screen using your mouse.

Context Menu: Right-click anywhere on the white bar to seamlessly toggle between modes or exit the application.

High DPI Support: Fully optimized for Windows 11 display scaling, ensuring the bar remains a crisp 40 pixels high on any monitor setup.

Minimalist Design: Clean interface with no taskbar icon to ensure zero distractions while you work.
