macOS fills the window's leading corner with the traffic lights and `TITLE_BAR_LEAD` reserves them 80px. Everywhere else that corner held nothing: the caption row's only contents are the rail's "+" and collapse at the rail's right edge and the corner chrome at the window's, so the left third of the row read as unfinished rather than restrained — while Windows treats the top-left as the app's identity slot. Three parts, all of them about that row: - `window_mark()` draws the "duo" mark (the app icon's own art) at the head of the rail on `CONTENT_INSET`, the line the search box and every row label below it start on, and follows the rail's controls into the title strip when the sidebar collapses. It is drawn, never clicked: no hover capsule, and deliberately no `occlude()`, so the drag region underneath still takes the press and the strip stays grabbable. - The rail's stand-in row now reserves the same hairline the real `TitleBar` draws inside its own height. Without it the bar centred content on 19.5 and the rail on 20, and the mark hopped half a pixel as collapsing the rail handed it from one to the other. - With the detail panel open off macOS the bar is hoisted above `[terminal | panel]` so the window controls can reach the corner, which left the code and diff overlays — anchored to the terminal column — starting 40px down, with headers drawn to *be* the title bar landing a row low. They now hang on the row that owns the bar, inset by the panel's width. Covering the caption row that way needs the headers to carry its gestures, which neither ever did with the panel open or closed: `title_bar_drag()` gives both (and the rail's row, which grew the same wiring by hand) drag-to-move and double-click-to-zoom, and their controls are `occlude()`d so HTCAPTION stops eating the clicks.

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
