   - add an `Export query` button to the graph that saves the result of executing the query in `JSON`. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5497).
 * FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add `-vmui.defaultTimezone` flag to set a default timezone. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5375) and [these docs](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/app/vmui#timezone-configuration).
 * FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): include UTC in the timezone selection dropdown for standardized time referencing. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5375).
+* FEATURE: [vmui](https://docs.victoriametrics.com/#vmui): add the ability to expand/collapse all tracing entries and download tracing data in .json format. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5677).

 * BUGFIX: properly return the list of matching label names and label values from [`/api/v1/labels`](https://docs.victoriametrics.com/url-examples.html#apiv1labels) and [`/api/v1/label/.../values`](https://docs.victoriametrics.com/url-examples.html#apiv1labelvalues) when the database contains more than `-search.maxUniqueTimeseries` unique [time series](https://docs.victoriametrics.com/keyConcepts.html#time-series) on the selected time range. Previously VictoriaMetrics could return `the number of matching timeseries exceeds ...`  error in this case. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5055).
