v1.3.0

Added

• Grand total — a strip beneath the Today / This Month / All Time cards in the
  dashboard, summing your all-time spend, messages, and active time in one place.
  Active time reuses the session active-time measure (idle gaps longer than 15 minutes
  are excluded), so it reflects time actually spent working, not wall-clock. On a
  subscription the spend is labeled "≈ API" to match the rest of the dashboard.

Fixed

• Plan limits now stay live across multiple editor windows. With more than one
  window open (and especially on a Max plan), each window used to poll Anthropic's
  usage endpoint independently; the extra traffic could get a window rate-limited
  (HTTP 429) and stuck showing a stale "Updated Nd ago" reading until you reloaded it.
  A successful fetch is now published to a small shared file that every window reads,
  so all open windows share one fetch (~one request between them instead of one each),
  and a rate-limited window shows a sibling window's fresh data instead of falling back
  to a stale cache. The shared file holds only the usage figures and a timestamp — never
  your credentials — and lives alongside Claude's own files (honoring CLAUDE_CONFIG_DIR)
  so Cursor and VS Code on the same account coordinate too.
