The panel's title-bar-height top zone carried seven controls belonging to three different layers: four panel tabs, the panel toggle, the "..." menu, and the workspace chip. All seven at chrome scale, in a column the user can drag down to MIN_WIDTH. The row wants 268px there — it overflows by 68px before anything else goes wrong. The layers are the real defect; the crowding is a symptom. Switching to Files is "what does this panel show", the workspace chip is "which machine am I on", and they sat side by side, same size, same weight. Three changes, none of which touch the window layout — both columns stay full-height and the corner controls stay where they are: - The workspace chip moves to the head of the rail, as a full row with the workspace's name rather than a monogram in a corner. The rail below it enumerates that workspace's tabs, so this is where the name belongs; it also stops a window-scoped control from competing for the panel's width. Note it is *not* folded into the repo group headers under it — those are repositories, and one workspace holds several. - The panel's tab tiles drop to TILE_SIZE_SM. That constant exists for tiles inside a panel, which is exactly what these are, and the one size step separates them from the window chrome sharing their row without spending a divider on it. - On macOS panel_title draws nothing. The tile row above it already says which tab you are on, and so does the content — a file tree is Files, a diff is Changes. It cost a whole row: tiles, then a title, then a search box, before one line of content. Changes' file count moves into that tab's tooltip, where it stays readable without switching tabs. Outline's count does not survive: it needs the active leaf, which needs a &Window right_panel_tabs has no reason to take, and its list is one click away. A tab passing `trailing` still gets the row; none currently do. Off macOS nothing changes: the panel hangs below a spanning title bar there, and panel_title is still that panel's tab switcher. The top zone now needs ~164px against a 200px minimum.
tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume
