Combined Anthropic and OpenAI quota display in the top bar. Session, weekly, model-scoped, primary, secondary, and additional limit windows. Independently ordered Icon, Usage, pace Delta, and Window Time components per provider. Green ahead-of-pace, yellow on-pace, and red behind/exhausted Delta feedback. Automatic discovery of existing Claude Code and Codex CLI sessions. Built-in Anthropic and OpenAI browser login; OpenAI device-code fallback. Extension-owned refresh tokens stored only in GNOME Secret Service. Native GNOME/libadwaita Preferences and manual connection checks. Optional private, read-only web dashboard for localhost or an exact Tailscale/NetBird IP. Pure-light and AMOLED themes plus a local Three.js drone simulation with browser controls. Last-good quota preservation for transient provider failures, including explicit HTTP 429 cached state. Original and dashboard-style provider icon variants. Portrait and side-by-side Landscape layouts for the expanded GNOME indicator menu. Claude Code and Codex do not need to be installed for built-in login. When they are installed, their existing sessions are used read-only and remain owned by those applications.
