Audited every page under docs/ against the source. Fixes for what the code actually does: - agents: the status vocabulary is idle/working/waiting/done, not running/waiting/idle; hook rows grow a separate Uninstall button; the Settings table labels read "Copilot CLI" and "Grok Build"; Copy Session ID lives in the tab's context menu, not the pane's - cli: `pane ls --all` reports the owning workspace id, not "tty7-cli"; document bare `tty7 [PATH]` as the GUI launcher it is instead of listing it as unimplemented; note `active_tab` and the `diagnostics` array; wait also defaults to $TTY7_PANE - git: the branch dropdown is a plain list with no search box and no stash-and-switch, and checkout is not a palette command; quote the diff overlay's own overflow notice rather than the sidebar's - window: the unread marker tracks a finished agent turn, not any output; rows cannot be dragged across groups; the sidebar and `tty7 tab ls` resolve labels differently; drop Toggle Commit History and Checkout to from the palette's Git group; ~/.ssh/config aliases are not palette entries - terminal: Ctrl+R dedups by command text and shows no directory; Esc does not dismiss a ghost suggestion; document Cmd+Enter - remote: GSSAPI is an ordinary Auth choice, not a managed-connection-only mechanism - fonts: Maple Mono NF CN leads the chain on Windows and Linux only; list the real per-platform defaults - settings paths: the three Links settings and per-pane history were filed under the wrong sections

|

|
||
**Settings → Appearance → Typography** covers the everyday choices; the rest is
|
||
`config.json`.
|
||
|
||
| Setting | Default | |
|
||
|---|---|---|
|
||
| **Font family** | Hack | Picked from fonts installed on your system |
|
||
| **Font size** | 15 px | The terminal grid |
|
||
| **Interface font size** | 16 px | Everything outside the grid (12–24) |
|
||
| **Line height** | 1.4 | A multiple of the font size |
|
||
| **Bold font** / **Italic font** | — | Distinct faces, when you want them |
|
||
| **Font ligatures** | off | Contextual alternates stay off unless you ask |
|
||
|
||
## Hack is bundled
|
||
|
||
The default font ships inside the binary. It renders identically on every
|
||
machine without relying on a system install, so a fresh laptop looks like the
|
||
one you set up last year.
|
||
|
||
## Fallbacks
|
||
|
||
`font_family` is the primary face; `font_fallbacks` is an ordered list tried in
|
||
turn for anything the primary lacks.
|
||
|
||
```json
|
||
{
|
||
"font_family": "JetBrains Mono",
|
||
"font_fallbacks": ["Maple Mono NF CN", "PingFang SC", "Apple Color Emoji"]
|
||
}
|
||
```
|
||
|
||
Leave `font_fallbacks` out and you get the platform's default chain:
|
||
|
||
| | Default fallbacks, in order |
|
||
|---|---|
|
||
| **macOS** | Menlo · Hasklug Nerd Font Mono · Maple Mono NF CN · PingFang SC · Apple Color Emoji |
|
||
| **Windows** | Maple Mono NF CN · Cascadia Mono · Microsoft YaHei · Segoe UI Emoji |
|
||
| **Linux** | Maple Mono NF CN · DejaVu Sans Mono · Noto Sans CJK SC · Noto Color Emoji |
|
||
|
||
Each ends in faces the host OS actually ships, and those stock names are
|
||
appended to whatever list you write yourself — so a `config.json` copied from
|
||
another platform still resolves.
|
||
|
||
## OpenType features
|
||
|
||
`font_features` passes tags straight through to the shaper:
|
||
|
||
```json
|
||
{
|
||
"font_features": { "calt": true, "liga": 1, "ss01": true, "zero": false }
|
||
}
|
||
```
|
||
|
||
A tag must be four alphanumeric characters; `true`/`false` map to `1`/`0`.
|
||
Anything malformed is skipped with a log line rather than failing the whole
|
||
config.
|
||
|
||
## CJK and the two-column grid
|
||
|
||
<Info>
|
||
A cell is one advance of the primary face, and a wide (CJK) character is
|
||
pinned to exactly two of them. A CJK fallback sits flush in its slot only if
|
||
its ideographs advance **twice** the primary's Latin advance.
|
||
</Info>
|
||
|
||
Bundled Hack advances 0.60205em, so a two-column slot is 1.2041em — while every
|
||
stock CJK face (Microsoft YaHei, PingFang SC, Noto Sans CJK) advances 1.0em.
|
||
Those glyphs get left-aligned in the slot, leaving a ~0.2em gap on the right of
|
||
every character.
|
||
|
||
[Maple Mono NF CN](https://github.com/subframe7536/maple-font) is in every
|
||
platform's default chain for exactly this reason: 0.6em Latin, 1.2em CJK, an
|
||
exact two-cell fit against Hack. It leads the chain on Windows and Linux, and on
|
||
macOS sits behind Menlo and Hasklug, which cover Latin and Nerd Font glyphs
|
||
first. It is referenced by name only, never bundled (~20 MB per weight) —
|
||
install it and tty7 picks it up with no config change.
|
||
|
||
If you want CJK set *tight* rather than merely even, change the **primary** face
|
||
instead. One that advances 0.5em — Sarasa Mono SC, say — makes two columns
|
||
exactly 1.0em.
