-| **RSA** | RSA 2048/4096 | レガシー互換性、ユニバーサルサポート |
-| **証明書** | CA 署名 | エンタープライズ環境、短期認証 |
-
-**機能：**
-- 🔑 カスタマイズ可能なビット長でキーを生成
-- 📥 PEM/OpenSSH 形式のキーをインポート
-- 👤 再利用可能なアイデンティティを作成（ユーザー名＋認証方式）

+<a name="main-window"></a>
+## Main Window
 
-The Vault view is your command center for managing all SSH connections. Create hierarchical groups with right-click context menus, drag hosts between groups, and use breadcrumb navigation to quickly traverse your host tree. Each host displays its connection status, OS icon, and quick-connect button. Switch between grid and list views based on your preference, and use the powerful search to filter hosts by name, hostname, tags, or group.
+The main window is designed for long-running SSH workflows: quick access to sessions, navigation, and core tools in one place.

+![Vault Tree View (Dark)](screenshots/treeview-dark.png)
 
-Powered by xterm.js with WebGL acceleration, the terminal delivers a smooth, responsive experience. Split your workspace horizontally or vertically to monitor multiple sessions simultaneously. Enable broadcast mode to send commands to all terminals at once — perfect for fleet management. The theme customization panel offers 50+ color schemes with live preview, adjustable font size, and multiple font family options including JetBrains Mono and Fira Code.

-**Split Windows**
+<a name="split-terminals"></a>
+## Split Terminals
 
-**Broadcast Mode**
+Split panes help you monitor multiple servers/services at the same time (deploy + logs + metrics) without juggling windows.
 
-Type once, execute everywhere. Great for maintaining multiple servers simultaneously.

-<a name="sftp"></a>
-## SFTP
-
-The dual-pane SFTP browser supports local-to-remote and remote-to-remote file transfers. Navigate directories with single-click, drag files between panes, and monitor transfer progress in real-time. The interface shows file permissions, sizes, and modification dates. Queue multiple transfers and watch them complete with detailed speed and progress indicators. Context menus provide quick access to rename, delete, download, and upload operations.

-
-<a name="keychain"></a>
-## Keychain
-
-The Keychain is your secure vault for SSH credentials. Generate new keys, import existing ones, or manage SSH certificates for enterprise authentication.
-
-| Key Type | Algorithm | Recommended Use |
-|----------|-----------|----------------|
-| **ED25519** | EdDSA | Modern, fast, most secure (recommended) |
-| **ECDSA** | NIST P-256/384/521 | Good security, widely supported |
-| **RSA** | RSA 2048/4096 | Legacy compatibility, universal support |
-| **Certificate** | CA-signed | Enterprise environments, short-lived auth |
-
-**Features:**
-- 🔑 Generate keys with customizable bit lengths
-- 📥 Import PEM/OpenSSH format keys
-- 👤 Create reusable identities (username + auth method)
-- 📤 One-click export public keys to remote hosts

-
-<a name="port-forwarding"></a>
-## Port Forwarding
-
-Set up SSH tunnels with an intuitive visual interface. Each tunnel shows real-time status with clear indicators for active, connecting, or error states. Save tunnel configurations for quick reuse across sessions.
-
-| Type | Direction | Use Case | Example |
-|------|-----------|----------|--------|
-| **Local** | Remote → Local | Access remote services on your machine | Forward remote MySQL `3306` to `localhost:3306` |
-| **Remote** | Local → Remote | Share local services with remote server | Expose local dev server to remote machine |
-| **Dynamic** | SOCKS5 Proxy | Secure browsing through SSH tunnel | Browse internet via encrypted SSH connection |
-
-![Port Forwarding](screenshots/port-forwadring.png)
-
-<a name="cloud-sync"></a>
-## Cloud Sync
-
-Keep your hosts, keys, snippets, and settings synchronized across all your devices with end-to-end encryption. Your master password encrypts all data locally before upload — the cloud provider never sees plaintext.
-
-| Provider | Best For | Setup Complexity |
-|----------|----------|------------------|
-| **GitHub Gist** | Quick setup, version history | ⭐ Easy |
-| **Google Drive** | Personal use, large storage | ⭐ Easy |
-| **OneDrive** | Microsoft ecosystem users | ⭐ Easy |
-| **S3-Compatible** | AWS, MinIO, Cloudflare R2, self-hosted | ⭐⭐ Medium |
-| **WebDAV** | Nextcloud, ownCloud, self-hosted | ⭐⭐ Medium |
-
-**What syncs:**
-- ✅ Hosts & connection settings
-- ✅ SSH keys & certificates
-- ✅ Identities & credentials
-- ✅ Snippets & scripts
-- ✅ Custom groups & tags
-- ✅ Port forwarding rules
-- ✅ Application preferences
-
-![Cloud Sync](screenshots/cloud-sync.png)
-
-<a name="themes--customization"></a>
-## Themes & Customization
-
-Make Netcatty truly yours with extensive customization options. Toggle between light and dark modes, or let the app follow your system preference. Pick any accent color to match your style. The application supports multiple languages including English and 简体中文, with more translations welcome via community contributions. All preferences sync across devices when cloud sync is enabled, so your personalized experience follows you everywhere.

+# 为什么是 Netcatty
+
+如果你需要同时维护多台服务器，Netcatty 更像是“工作台”而不是单一终端：
+
+- **以工作区为核心** —— 分屏 + 多会话并行，适合长期驻留的工作流
+- **Vault 管理** —— 网格/列表/树形视图，配合搜索与拖拽更顺手
+- **认真做的 SFTP** —— 内置编辑器 + 拖拽上传，文件操作更丝滑

+## 主界面
 
-Vault 视图是管理所有 SSH 连接的控制中心。通过右键菜单创建层级分组，在分组间拖拽主机，使用面包屑导航快速遍历主机树。每个主机显示连接状态、操作系统图标和快速连接按钮。根据偏好在网格和列表视图之间切换，使用强大的搜索按名称、主机名、标签或分组过滤主机。
+主界面围绕长期 SSH 工作流设计：把会话、导航和常用工具集中到同一处，减少切换成本。

-## 密钥管理
-
-密钥库是您存储 SSH 凭证的安全保险库。生成新密钥、导入已有密钥或管理企业认证的 SSH 证书。
-
-| 密钥类型 | 算法 | 推荐用途 |
-|---------|------|---------|
-| **ED25519** | EdDSA | 现代、快速、最安全（推荐） |
-| **ECDSA** | NIST P-256/384/521 | 安全性好、广泛支持 |
-| **RSA** | RSA 2048/4096 | 旧版兼容、通用支持 |
-| **证书** | CA 签名 | 企业环境、短期认证 |
-
-**功能：**
-- 🔑 生成可自定义位长的密钥
-- 📥 导入 PEM/OpenSSH 格式密钥
-- 👤 创建可复用身份（用户名 + 认证方式）
-- 📤 一键导出公钥到远程主机

-<a name="端口转发"></a>
-## 端口转发
-
-通过直观的可视化界面设置 SSH 隧道。每个隧道显示实时状态，清晰指示活动、连接中或错误状态。保存隧道配置以便跨会话快速复用。
-
-| 类型 | 方向 | 使用场景 | 示例 |
-|-----|-----|---------|-----|
-| **本地** | 远程 → 本地 | 在本机访问远程服务 | 将远程 MySQL `3306` 转发到 `localhost:3306` |
-| **远程** | 本地 → 远程 | 与远程服务器共享本地服务 | 将本地开发服务器暴露给远程机器 |
-| **动态** | SOCKS5 代理 | 通过 SSH 隧道安全浏览 | 通过加密 SSH 连接浏览互联网 |
