Searchable /config panel lets you adjust preferences instantly and indicates which changes need a restart. Live follow-up steering lets you send a prompt while Codex is responding, interrupting also stops active Code Mode cells and nested tool calls. Configurable leader key (default Ctrl+X) can be set in /keymap, with shortcut hints staying open until you choose or cancel. Background server restart is available from /daemon, with warnings about potential work loss and automatic reconnection. Parallel read-only tools such as skill, memory, and conversation-history lookups now run concurrently.
