+- When a usage request is rejected because the sign-in has expired, the app
+  runs `claude -p .` for Claude Code and `codex exec .` for Codex, for each

+  your usage.
 
 What the app stores locally:

 - Bubble size
+- Whether the bubbles are shown (**Show widget**)
 - Polling frequency
+- Auto-update check interval
 - Last update check time
