 This widget displays internet speed test results from your [Speedtest Tracker](https://docs.speedtest-tracker.dev/) instance,
 including the latest result, historical averages, and a live chart of the last 12 hours.
 
+Advanced view renders a source-labeled panel for every healthy integration. Each panel exposes that source's latest test, statistics, speed and ping charts, plus 12-hour, 24-hour, and truthful **Last 30** result ranges regardless of compact visibility switches. Compact mode keeps the responsive aggregate overview and names its healthy sources when multiple integrations are selected.
+
+When multiple Speedtest Tracker integrations are selected, results from healthy sources remain visible if another source fails. A warning indicator identifies each unavailable integration without exposing private request details. If every selected integration fails, the widget reports an error; if cached data remains visible after a later total failure, a stale-data warning is shown.
