Notes+

A Fabric mod for Minecraft 1.21.11 that adds an in-game notes editor, calculator, and timer — all accessible as floating overlay windows without pausing the game.

Features

Notes Editor (F7)

• Multi-file note system with a sidebar file browser
• Nested folder organization with drag-to-reorder
• Markdown rendering: headings, bold, italic, strikethrough, underline, inline code, blockquotes, bullets, checkboxes, code blocks
• Clickable note links with [[Note Name]] syntax
• Word-boundary wrapping with smart bullet/heading indentation
• Text selection, copy/cut/paste, undo via keyboard
• Right-click context menu with configurable actions
• Insert player coordinates (dimension-aware)
• Export to clipboard, desktop, or system file manager
• Quick Note shortcut for rapid capture
• Autosave (2-second idle) and manual save (Ctrl+S)
• Per-world notes (singleplayer) or shared notes (multiplayer)
• Configurable window opacity and color scheme

Calculator (F6)

• Standard arithmetic with recursive-descent expression parser
• Supports +, -, *, /, parentheses, decimals, and negative numbers
• Calculation history (per-world, up to 50 entries)
• iOS-style clear: C clears expression, double-tap C (AC) clears all history
• Send result to Notes with one click
• Full keyboard and mouse input

Timer (F8)

• Countdown timer with digit-entry input and preset buttons
• Stopwatch mode with lap times
• Keyboard shortcuts: Space (start/pause), R (reset), L (lap), Tab (switch mode)

• Sound notification on timer completion

• Drag, resize, and adjust opacity in the HUD Configuration screen
• Toggle HUD visibility and interact with pinned elements via configurable keys

• Per-keybind restore-default button when changed
• Color scheme customization with HSB color picker
• HUD display toggles and background visibility
• Right-click context menu item toggles
