At 1200x800 — an ordinary window size — the SSH host form was cut off by the window edge: the Connect button was sliced in half, the Name, Host and User fields had no visible right edge, and the Auth control lost its last option entirely. "2FA" was off screen, so at that size an authentication method could not be selected at all. Nothing scrolled horizontally, so there was no way to reach any of it short of resizing the window. Two causes, both in the layout: - `#ssh-detail` is `flex_1` but had no `min_w_0`. Flex items default to `min-width: auto`, so the column sized itself to its content instead of to the space left over after the 280px host list, and the overflow went past the window. - `settings_row` then had no way to cope: the label column could shrink to nothing while the control could not shrink at all. Adding `min_w_0` alone made it worse — at 900px the labels collapsed to one word, then one *letter*, per line. The row now wraps and the label column has a 200px floor, which is the usual settings-pane behaviour: side by side while there is room, control stacked beneath the label when there is not. | Window | Before | After | |---|---|---| | 1200px | Connect halved, three fields and "2FA" off screen | everything fits side by side | | 900px | same, worse | rows stack; all six auth methods reachable | | wide | fine | unchanged — the 720px cap still holds | Checked on screen at 1200 and 900, and on Appearance and Terminal at 1200 to confirm the wrap does not fire where there is room: those two pages are pixel-identical to before.
tty7
A terminal workbench: persistent sessions, remote work, agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
- Editor-grade input — suggestions, completion, highlighting, history search
- Remote development — files, repos, panes, and git data stay on the remote machine
- Native SSH — profiles, SFTP, port forwarding, and jump hosts
- Agent-aware — Claude Code, Codex & co.: status, notifications, git context
- CLI + Skills — agents create panes, run commands, and inspect output
