v1.1.0

Added

• A Usage popup. Bind switchboard.usage or open it from the central menu to see how much of
  each AI subscription is spent and when it resets. Each agent gets a donut for the window closest
  to running out, a bar for every other window, and the numbers that give the percentage its
  context: what the session spent, how much of the context window the last turn used, whether
  credits are on. Every card dates itself — as of 12m ago — because Codex reports whatever its
  last session wrote, and a two-day-old percentage read as current is the mistake this popup exists
  to prevent. Resets are given both ways, in 1d 12h and resets 08:53 Wed.

  Codex reads the exact numbers OpenAI returns, straight out of its own session log, with no
  network at all. Claude Code publishes nothing to disk, so its card asks the same endpoint the
  in-session /usage command asks, using the OAuth token Claude Code already stores; that request
  runs on a worker with a timeout, so the popup opens instantly with Codex on screen and fills
  Claude in when it lands. Claude also grades its own limits, and the card colours them the way the
  provider grades them rather than by a threshold of ours; anything ungraded falls back to
  usage.warn_percent and usage.alert_percent.

  Each card names the account it is reporting on — the two agents are routinely signed in as two
  different people, and a quota means little without knowing whose it is. Codex's address comes
  from the ID token it stores, Claude's from the profile Claude Code caches, and that profile is
  also where the Claude card gets its plan, since the usage endpoint names none.

  Press r to read both again. Any agent that cannot be read says why on its own card and leaves
  the other one alone. Choose the providers and thresholds under [usage], or from the settings
  overlay.

• Zen can hide Herdr's own chrome. The new zen.chrome setting (off by default, or
  panes / full) suppresses the pane borders and gaps, the scrollbar column, the tab row and
  the sidebar for the length of a zen session. None of those have a per-pane switch, so anything
  but off rewrites the matching [ui] keys in Herdr's own config.toml and reloads Herdr,
  then restores them exactly on the way out: comments and unmanaged keys survive, keys already at
  the wanted value are left alone, and your untouched config is copied to
  $XDG_STATE_HOME/herdr-switchboard/herdr-config.backup.toml before the first write. If a
  restore fails or Herdr is killed mid-session, herdr-switchboard zen chrome-restore puts it
  back. Herdr only applies sidebar_start_collapsed on its next launch, so full may leave the
  sidebar in place — zen measures that and says so rather than failing silently.

• Zen mode. switchboard.zen-toggle gives the current pane the screen: it moves to a tab of
  its own, centred at zen.width (default 70%) between two dimmed gutters, and toggling again
  puts it back where it was. switchboard.zen opens a picker to zen any pane instead of the
  current one. The gutters are dimmed by painting over them through Herdr's graphics API, which
  needs [experimental] kitty_graphics = true; without it the gutters are simply blank. Tune it
  with zen.width, zen.scrim, and zen.scrim_color, or from the settings overlay. Neighbouring
  panes are never touched — only the zen'd pane moves, and its running process survives the move.
  Leaving zen restores a two-pane tab exactly; a more deeply nested tab gets every pane back beside
  its former neighbour, with a notification when the split nesting could not be reproduced.

• An AI Agents picker. Bind switchboard.agents or open it from the central menu to list the
  AI integrations installed in Herdr. enter starts the selected AI in the origin pane, ctrl-t
  starts it in a new tab, and alt-w starts it in a new workspace; failed starts clean up any
  tab or workspace Switchboard created. The focused picker opens as a compact centered popup rather
  than a mostly empty full-screen overlay. This requires Herdr 0.8.0 or newer.

Changed

• The README is now a concise entry point instead of a monolithic reference. Quick start,
  feature discovery, core actions, and namespaced configuration stay on the front page; detailed
  keybindings, safety behaviour, Zen, Git, configuration, and architecture now live in focused
  guides under docs/. Stale pre-1.0 wording, flat configuration names, dependency scope, popup
  placement, update-version examples, and contributor checks were corrected at the same time.

Fixed

• Opening AI Agents or another popup from the Central Menu now waits for the menu popup to close,
  so Herdr no longer rejects the replacement as popup already open.
• The AI Agents picker now closes immediately after a selection while startup readiness is checked
  in the background; failed starts still clean up new tabs or workspaces and report the error with
  a notification.
• Linked development checkouts now rebuild their release binary when Rust sources or Cargo metadata
  are newer, instead of silently running an old same-version binary after source changes.
