Adds Calendar Live Overlay v0.0.1.

This mod displays a customizable monthly calendar directly on the desktop behind desktop icons.

Features:

• Monthly calendar desktop overlay
• Runs behind desktop icons
• Absolute or percentage-based positioning
• Multi-monitor support
• Configurable font family, size, weight, and style
• Custom text color with alpha transparency
• Optional German or English month/day names
• Monday or Sunday week start
• Optional month header
• Optional week numbers
• Optional leading zero day numbers
• Optional box drawing border
• Today highlighting with custom color, bold, and underline
• Weekend highlighting with custom color and opacity
• Optional custom colors for week numbers and weekday names
• Adjustable column and row spacing
• Header alignment options
• Optional background with color, padding, rounded corners, border, and blur

For best alignment, monospaced fonts are recommended, such as Cascadia Mono, Consolas, JetBrains Mono, or JetBrains Mono / Courier New. Proportional fonts can visually distort the calendar grid.

Tested locally on Windows 11.

Added screenshots for Calendar Live Overlay v0.0.1.

The screenshots show the calendar overlay with different font choices and layout behavior.

For best alignment, monospaced fonts are recommended, such as Cascadia Mono, Consolas, JetBrains Mono, or Courier New. Proportional fonts such as Arial, Calibri, or Verdana can visually distort the calendar grid because the calendar uses fixed-width text alignment.
