What is new in CodexIsland 0.3.0

# CodexIsland 0.3.0

A new way to read your limits, with five redesigned quota charts and a balanced notch peek.

- **Choose the chart that reads fastest.** Rails, Ring, Grid, History, and Stepped replace the old chart set. History uses recorded quota observations, with smoother paths and visible abrupt changes. Existing chart choices migrate automatically.
- **Read both sides of the notch.** The peek pairs usage and reset readings; a single-provider layout includes a compact quota gauge.
- **Keep quota readings on the right account.** Codex requests follow the selected account. Claude Code account changes invalidate cached credentials while retaining the five-minute automatic request floor and rate-limit cooldowns.
- **See Claude Enterprise monthly credits.** Limited and unlimited credit amounts are shown accurately, with independent monthly threshold alerts. Credits consumed are not billed charges.
- **Share cards in your chosen currency.** Localized totals, milestones, and card tiers agree with the displayed currency. SEK is now available, and cached exchange rates survive upgrades.
- **Clearer setup and contribution guidance.** Claude setup requires Terminal login through the Claude Code CLI. Issue forms, a PR template with required UI screenshots, and project-specific Codex review guidance are included.
