Quarters 0.5.0

Run many agents without losing track: who's waiting for you comes first
(⌘J), prompts queue up for when an agent finishes, usage shows per
project, and agent instructions are edited in place. Quarters itself got
much lighter when idle (about 2% of a CPU core, from about 20%), its side
panel folds, and every command is a keystroke away.

• Who's waiting for you. The ACTIVE list (and the start screen's) puts the
  sessions that finished while you looked elsewhere first, longest waiting
  first, with how long they've waited and whether the agent is asking you
  something. ⌘J (Session → Next Waiting for You), or a click on the title
  bar's "◐ waiting", opens the next one.

• Prompt queue. Line up prompts for a session in the side panel (QUEUE ·
  ＋ add prompt; reorder, remove); each is sent when the agent has finished
  the one before. Quarters waits while the agent asks a question or shows
  a permission prompt, and never types over a message you started in its
  input box; a prompt is sent once, and the next only after the agent
  worked on it. No "your turn" alert while prompts are waiting. On a
  phone, ⏭ in the message card queues what you typed while the agent works.
  Settings → Prompt queue.

• Usage by project. The side panel's USAGE shows the project's tokens
  today, over 7 and 30 days, a 14-day chart and its share of your week;
  View → Usage by Project (⇧⌘U) ranks every project (worktrees count as
  their project). Read from Claude Code's logs: input, output and cache
  writes. Settings → Usage by project.

• Agent instructions and notes. INSTRUCTIONS in the side panel opens the
  project's CLAUDE.md, AGENTS.md, GEMINI.md or CONVENTIONS.md in an editor
  (the file the project's agent reads is offered even before it exists; a
  CLAUDE.md that links to AGENTS.md is saved through the link), and won't
  save over a version the agent changed meanwhile. Notes are yours: kept
  with Quarters' settings, not in the project. Devices with less than full
  access can read them, not save. Settings → Agent instructions & notes.

• Much lighter when idle. The mascot animates when something happens and
  for a moment each minute, then stands still (its animation was redrawn
  60 times a second, always); nothing on a timer runs while the window is
  hidden, and less while Quarters isn't in front. git runs only when
  something may have changed (a commit, a checkout, a session's output)
  instead of every 2 seconds for the open project and every 15 for all;
  the project list is sent to windows when it changes instead of asked for
  every 3 seconds; ~/.claude.json and the session-log folders are read
  again only when they change. Measured on a Mac with 14 projects, idle
  in the background: about 20% of a CPU core before, 2% after.

• Terminals keep their fast GPU drawing: only the ones on screen and the
  few shown last hold a WebGL context (WebKit allows about 16 and took the
  oldest away, leaving it on the slow fallback for good).

• Remote access loads less: dialogs most visits never open (settings,
  editing a project, past conversations, diffs, the editor, usage, the
  shortcuts list) load the first time they open, and every file carries an
  ETag, so a phone revalidates instead of downloading the app again.

• The side panel's sections fold to one line (click the title); the bar
  above jumps to a section or folds them all. One look for all section
  titles.

• Every command by name: ⇧⌘P, or ">" in the jump list. Focus mode (⇧⌘↵)
  leaves only the terminal.

• A colour per project marks its tabs and the terminal's frame, from its
  name or chosen in its dialog ("color" in config.json). Settings →
  Appearance: System, Light or Dark, on each device.

• Quieter lists: idle projects show no status mark, a project listed in
  ACTIVE doesn't repeat its status in its group, and dialogs open with a
  short fade (none with reduced motion).
