多会话 · 分屏Sessions & Split View
把桌面级的多终端能力带到每一端。
会话标签
- 每个连接是一个标签。点标签栏 + 在当前窗口新建会话。
- 拖拽标签可重排顺序。
- ⌘W 关闭当前会话（Mac / iPad 硬件键盘）。
分屏
- Mac / iPad 点「分屏」即可并排显示所有会话，排布支持 自动 / 左右 / 上下 / 网格。
- iPhone 仅在 横屏 下分屏（竖屏并排太窄不可读）。
断线重连
会话假死 / 断线会被自动探测并重连；也可右键标签强制「重新连接」。
Mosh 兼容连接
主机可以选用 Mosh 兼容传输：它走 UDP，切换 Wi-Fi / 蜂窝网络、设备休眠唤醒之后会话都不会断，弱网下打字也不会卡顿堆积。
但它不保留滚动历史。这是协议本身的取舍，不是缺陷：该协议同步的是「当前这一屏应该长什么样」，而不是完整的输出字节流——滚出屏幕的内容在服务端就被丢弃了，从来没有经网络传过来。所以在 Mosh 兼容会话里往上翻是空的，跑 tail -f、seq 1 1000 这类持续输出时尤其明显。mosh 官方客户端同样如此。
- 需要回头翻阅输出 → 用 SSH 连接，滚动历史完整保留（回滚行数可在「设置 ▸ 终端」调整）。
- 既要漫游又要历史 → 在远端跑 tmux 或 screen，由它接管历史，用 Ctrl-b [ 进入复制模式翻页。
Desktop-class multi-terminal on every device.
Session tabs
- Each connection is a tab. Tap + in the tab bar to open a new session in the current window.
- Drag tabs to reorder.
- ⌘W closes the current session (Mac / iPad hardware keyboard).
Split View
- On Mac / iPad, tap “Split” to show all sessions side by side — arrange auto / columns / rows / grid.
- On iPhone, split is available in landscape only (portrait is too narrow to read).
Auto-reconnect
Stalled / dropped sessions are detected and reconnected automatically; you can also force “Reconnect” from a tab’s context menu.
Mosh-compatible connections
A host can use the Mosh-compatible transport. It runs over UDP, so sessions survive Wi-Fi ↔ cellular switches and device sleep, and typing stays responsive on lossy links.
It keeps no scrollback. That is inherent to the protocol, not a defect: it synchronises what the screen should look like right now rather than the full stream of output — lines that scroll off are discarded on the server and never travel over the network. Scrolling up in a Mosh-compatible session therefore shows nothing, which is most obvious with continuous output such as tail -f or seq 1 1000. The official mosh client behaves the same way.
- Need to read back through output → use SSH, where scrollback is kept in full (buffer size is configurable under Settings ▸ Terminal).
- Want both roaming and history → run tmux or screen on the server and page through its copy mode with Ctrl-b [.
