* feat(settings): redesign theme picker with a slide-in panel Redesign the Appearance page's theme UI: - Replace the inline theme gallery with a compact "Current theme" card (preview + name + light/dark) that opens a searchable theme picker in a right-hand panel; applying a theme keeps the panel open so several looks can be tried in a row. - Add `theme_panel_open` / `theme_search` to `SettingsState`, plus toggle/close helpers and an `active_settings_mut` accessor. - Share one `theme_preview` between the card and the panel cards; keep the existing bar-based preview shape. - Group the custom-theme controls (duplicate / color editor / open folder) under the Theme section instead of stranding them at the foot of the page, and drop the near-black `.primary()` fill on the Duplicate button so it fits the soft, mostly-outline sheet. * style: rustfmt theme panel border_color --------- Co-authored-by: l0ng-ai <24760907+l0ng-ai@users.noreply.github.com>

Why tty7
- Fast — about 2× the throughput of Alacritty, Ghostty, or Kitty on the same hardware (benchmarks)
- A modern prompt — completion, syntax highlighting, and history search built in; no plugins to assemble
- Sessions that survive — close the window or quit the app, your shells keep running; no tmux
- Zero config — zsh, bash, fish, and PowerShell work out of the box
Native builds for macOS, Windows, and Linux ship with every release.
Install
Download the build for your platform from Releases:
- macOS —
tty7-<version>-macos-arm64.dmg(Apple Silicon) or…-x86_64.dmg(Intel); open it and dragtty7.appinto Applications. - Windows —
…-windows-x86_64-setup.exe(installer: Start Menu shortcut + uninstall entry), or…-windows-x86_64.zip(portable: unzip and runtty7.exe). - Linux —
…-linux-x86_64.tar.gz; extract and run./tty7(needs the usual x11/wayland runtime libraries).
Features
At the prompt
- Ghost suggestions — your history completes the whole line as you type; → to accept
- Tab completion that explains — every flag and subcommand with its description, for ~100 common commands
- Syntax highlighting — as you type, nothing to install
- Fuzzy history search — ⌃ R shows what you ran, where, and whether it failed
- History from day one — your existing shell history just works, and carries across sessions
- Real line editing — selection, word motion, undo
In the window
- Tabs & splits — always open in the current directory
- Command palette ⌘ P · scrollback search ⌘ F
- ⌘-click links · desktop notifications
- Eight themes · CJK / IME input
Benchmarks
All four terminals measured back-to-back on the same machine, same day, same 155×40 grid — Apple M1 Pro, macOS 26.3.1, five-run averages (2026-07-04):
| tty7 | Alacritty | Ghostty | Kitty | |
|---|---|---|---|---|
Plaintext IO — 11 MB cat (lower = better) |
95 ms | 239 ms | 179 ms | 185 ms |
| DOOM-fire frame rate (higher = better) | 888 fps | 485 fps | 552 fps | 617 fps |
| Cold-launch memory | 116 MB¹ | 105 MB | 128 MB | 130 MB |
¹ GUI 105 MB + the persistent daemon 11 MB.
Where the speed comes from:
- The PTY is read at device speed and parsed in large batches, off the render path
- Hot paths are lock-free — a big
catnever waits on drawing - The daemon buffers up to 16 MiB ahead of the window before backpressure applies
Methodology (how each terminal is driven, grid fairness, known pitfalls) and
one-command reproduction live in scripts/bench/ —
run it yourself.
Keybindings
Keys are shown in macOS notation — on Windows and Linux, read ⌘ as Ctrl. Open Settings with ⌘ , to browse or remap them all. The essentials:
| ⌘ T · ⌘ W · ⌘ ⇧ T | new tab · close tab · reopen closed tab |
| ⌘ D · ⌘ ⇧ D | split right · split down |
| ⌘ ] · ⌘ [ | next pane · previous pane |
| ⌘ ⏎ · ⌘ ⇧ ⏎ | toggle fullscreen · maximize / restore the pane |
| ⌘ K | clear the screen and scrollback |
| ⌘ P | command palette |
| ⌘ F | search the scrollback |
| ⌃ R | fuzzy-search shell history |
| ⌘ + · ⌘ − · ⌘ 0 | font size up · down · reset |
The full list — and any overrides — lives in Settings → Keybindings.
