+**Right sidebar tools**

+- They follow the current remote terminal and read and run on that terminal's own connection, with no second login. ⌘⌥B (Ctrl+Alt+B elsewhere) shows or hides them.
+- System monitor: system details, CPU (per core too), memory, network rates and disk use, refreshed every 2 seconds.
+- Network connections, processes and services: search and filter, process details, ending processes, starting, stopping and restarting systemd services, switching them on at boot, and their logs. These three and the monitor are for Linux only.
+- Docker: containers grouped by compose project, with start, stop, restart, details and logs, plus volumes, images and networks. When not root, passwordless sudo is used (for services as well).
+- Command history reads `~/.bash_history` on the host, and snippets, shared by every host, can be sorted into categories; click one to type it into the terminal, or run it straight away.

 **SFTP**
 
 - A dual-pane browser modeled on WinSCP Commander: symmetric local and remote panes with WinSCP's columns, path labels, bookmarks and shortcuts (F5, F2, F7, F8…).

+- 跟着当前的远程终端，在这条终端自己的连接上读取和执行，不另外登录；⌘⌥B（其他平台 Ctrl+Alt+B）显示或隐藏。
+- 系统监控：系统信息、CPU（含每个核）、内存、网卡速率和磁盘占用，每 2 秒刷新。
+- 网络连接、进程管理和系统服务：搜索和筛选，查看进程详情、结束进程，启动、停止、重启 systemd 服务，开关开机启动，查看日志。这三项和系统监控只支持 Linux。
+- Docker：按 compose 项目列出容器，启停、重启、看详情和日志，管理卷、镜像和网络。不是 root 时用免密码的 sudo（系统服务也是）。
+- 历史命令读主机上的 `~/.bash_history`，命令片段所有主机共用、可以分类；点一下输入到终端，或直接执行。
