## Philosophy
- **Paper first** — Every paper is an independent window that lives directly on the desktop, with no layered management console to open first.
- **Ready immediately** — Write when you want, check things off when done; everything saves automatically and the interaction path stays short.
- **No unnecessary management** — PaperTodo deliberately avoids complex project-management models, reducing the mental overhead of everyday capture.
- **Native & lightweight** — Built natively with WPF, without a Web wrapper, for fast startup and low resource use.
- **Restrained interaction** — The UI stays clean and low-distraction: quiet when idle, immediately available when needed.
> No unnecessary interaction layers. No unnecessary visual focus.

## Core Features
### 1. Two Basic Paper Types
- **Todo Paper**: A clean, efficient checklist with drag-and-drop ordering, continuous swipe multi-selection, and smart splitting of multi-line paste; completed items can be cleared automatically or moved to the bottom.
- **Note Paper**: Lightweight Markdown and visual notes with three levels of real-time rendering, natural editing/reading flow, and support for pasting or dropping local images.
### 2. Edge Capsules & Live Preview Cards
- **Collapse & Dock**: Click the top-right button or press `Ctrl+W` to collapse a paper into a compact capsule that automatically docks to a screen edge and frees up desktop space.
- **Hover Preview Cards (Preview)**: Hover an edge capsule to smoothly open a lightweight interactive preview card and inspect content without opening the full paper window:
- **Todo Preview**: Scroll, check, or uncheck visible tasks directly in the hover card; click the card background to open the full paper.
- **Note Preview**: Instantly renders Markdown body layout and image placeholders.
- **Intent Prediction & Seamless Handoff**: Built-in pointer-intent prediction keeps transitions smooth while moving across adjacent capsules and retracts automatically when the pointer leaves.
- **Multi-Monitor Flow & Master Capsule**: Drag capsules across displays and edges; the master capsule at the top can collapse the whole queue and can be dragged to adjust the queue's starting height.
### 3. New Plugin System (Preview)
- **Desktop Micro-App Expansion**: Papers are not limited to notes—you can switch them into clocks, focus Pomodoro timers, review pools, and other rich plugins: a next-generation take on Windows desktop widgets.
- **Deep Capsule & Top-Bar Integration**: Plugins can collapse into dedicated capsules, provide edge-hover cards and custom top-bar actions, while keeping their data stored independently.
- **Drop-in Use**: Place a plugin folder in `plugins/` and PaperTodo can recognize it directly. To build your own plugin, see the [Plugin Development Manual](plugin-samples/README.md).
### 4. Ultra-Smooth Native Experience & High-Refresh Tuning
- **Full high-refresh optimization**: Paper folding/unfolding, edge drawer motion, card handoff, and cross-monitor dragging are deeply tuned for frame pacing, with full support for 120Hz/144Hz/165Hz+ displays for a smooth, stutter-free feel.
- **Pure native responsiveness**: Built with .NET 10 and native WPF without Web-wrapper overhead, aiming for millisecond-level interaction, very low memory/CPU use, and unobtrusive always-on operation.
- **Incremental rendering for long notes**: Note input uses localized incremental parsing so long text-and-image notes remain responsive and IME input stays smooth.
- **Smooth multi-monitor and mixed-DPI flow**: Deeply adapted for multi-display setups with different scaling factors, keeping cross-screen dragging and edge docking precise without flicker or distortion.
### 5. Universal Todo Linking & Script Capsules
- **Quick Launch & Universal Linking**: Drag the link icon from another paper's top bar, or drop a file/folder from File Explorer onto a todo item, then click it to jump straight to the target.
- **Script Capsules (PowerShell)**: Put `!p` or `!power` on the first line of a note to turn it into a script runner; when collapsed it becomes a lightning capsule that executes the script when clicked.
### 6. Advanced Labs Features (Preview)
- **Local MCP Interface**: Start PaperTodo with `--mcp` to expose a standard MCP service, allowing authorized external AI assistants such as Claude or Cursor to securely read, write, and manage todos and notes.
- **Third-Party Window Tethering**: Drag to attach a paper to any third-party app window so it follows that window smoothly as it moves, minimizes, and restores.
- **Scheduled Reminders**: Todo items support custom countdown reminders with tray notifications and alert sounds when due.
- **Idle Behavior & Desktop Integration**: Papers can auto-collapse into capsules on focus loss and compact their title bar while idle; global shortcuts can send papers behind other windows and enable mouse click-through for deeper desktop integration.
### 7. Customization & Data Ownership
- **Appearance Customization**: Follow system/light/dark themes, choose from Warm Paper, Ink, Forest, and Rosy palettes, use a custom font by placing `papertodo.ttf`, and switch between multiple UI languages.
- **Local Control**: Data and images stay in the application directory (`data.json` and `note-assets.lmdb`), with automatic snapshot backups before writes and full offline operation.

## Download & Run
PaperTodo is a portable single-file application and requires no installation. Download the version you need from [Releases](https://github.com/snownico0722/PaperTodo/releases/latest):
- **`PaperTodo-...-self-contained.exe` (Recommended)**: Includes the .NET runtime and can be launched directly after download.
- **`PaperTodo-...-no-runtime.exe`**: Smaller download for systems that already have .NET 10 Desktop Runtime (x64) installed.
> **Tip**: Keep the executable in a dedicated writable directory such as `D:\Apps\PaperTodo\`. Avoid read-only locations or temporary extraction folders. Place `PaperTodo.ico` in the application directory to use it as a custom tray icon.
On first launch, papers appear on the desktop and the PaperTodo tray icon remains available. If papers are covered or moved off-screen, **double-click the tray icon** to show and retrieve all papers.

## 设计理念
- **纸片优先** — 每张纸都是独立窗口,直接常驻桌面,无需打开层级复杂的管理后台。
- **即时使用** — 想记就写,勾选即完;所有内容自动保存,操作路径极短。
- **无需管理** — 不刻意承载复杂的项目管理逻辑,降低日常记录的心智负担。
- **原生轻量** — 基于 WPF 原生开发,拒绝 Web 套壳,启动快速且资源占用低。
- **交互克制** — 界面干净低干扰,该安静时安静,需要时随时呼出。
> 拒绝长出非必要的交互层级和视觉焦点负担。
