 ## Features
 
 - **Lightweight runtime**: low backend overhead, browser-based control panel.
-- **Multi-session management**: create, switch, rename, and delete sessions with automatic history persistence.
-- **Session resume**: context continuity via `--resume`; you can also reattach via SSH + tmux when needed.
+- **Multi-session management**: create, switch, rename, and delete sessions; deleting a session also removes the local Claude history record.
+- **Session resume**: context continuity via `--resume`; you can also reattach via SSH + `tmux attach -t claude` when needed.
 - **Background task support**: Claude processes continue after browser disconnect and notify you on completion.
 - **Multi-channel notifications**: PushPlus / Telegram / ServerChan / Feishu bot / QQ (Qmsg), configurable in Web UI.
 - **Process persistence**: detached subprocess + PID files; running tasks survive service restarts.
-- **Mobile friendly**: responsive layout with PWA notifications.
+- **Multi-API switching**: configure multiple API profiles and switch between them instantly from the UI.
 - **Password-based auth**: initial password generation, forced first-login reset, and password change in Web UI.

 ## 功能特性
 
-- **超轻量** — 后端性能占用少，前端通过web访问，不易被杀后台
-- **多会话管理** — 创建、切换、重命名、删除会话，自动保存历史
-- **会话续接** — 基于 `--resume` 实现跨消息上下文保持，也可通过SSH使用tmux attach -t claude命令加入会话

 - **后台任务** — 关闭浏览器后 Claude 进程继续运行，完成后推送通知
 - **多渠道通知** — 支持 PushPlus / Telegram / Server酱 / 飞书机器人 / QQ（Qmsg），Web UI 内可视化配置
 - **进程持久化** — detached 进程 + PID 文件，服务重启不丢失运行中的任务
-- **移动端适配** — 响应式布局，支持 PWA 通知
+- **多 API 切换** — 可配置多个 API 方案，UI 中一键切换，即时生效
 - **密码认证** — 自动生成初始密码、首次登录强制改密、Web UI 修改密码
