 The Overview contains live counters, charts and optional backend, cache, PHP, Docker and Stream cards. Under **Settings → Appearance → Dashboard layout** or the Overview editor, configure visibility, order, card width, density and the number of history samples. A hidden card stops consuming its optional browser-side visualization work but does not turn off its underlying proxy feature.
 
+Quick-health tiles shown by default since 0.35.2:
+
+| Tile | Shows |
+|---|---|
+| **Healthy backends** | Monitored backend members passing health checks as `up / total`, with the names of failing members. |
+| **Error share** | Percentage of HTTP requests that ended with an error during the last sampling interval. |
+| **Rejected by limits / s** | Requests and connections refused by `--max-connections` / `--max-inflight`; sustained values mean the limits are too low for the load. |
+| **Nearest certificate expiry** | Days until the earliest installed certificate expires; the bar is full at 90 days or more. |
+
+Existing layouts receive these tiles at the end of the Overview; hide or move them in the layout editor.

 The unlocked Overview layout exposes a single **Save and lock** action (plus Cancel), removing the redundant lock-and-save button.
 
 **Dashboard Presets** supports up to **16 named layouts per administrator**. Save, load, rename, overwrite and delete presets; a factory layout can be restored. Presets preserve the dashboard arrangement, not the live traffic values. Interface theme, scale and other display settings are also account-scoped and do not alter proxy routing or rewrite shared configuration.
