I want to suggest a few improvements for the Datasets section.

1. It would be very convenient to see where a particular data set is used. To make this possible, delete the unused ones. In the process of configuring various reports, old settings accumulate that are lying idle. Unfortunately, it is currently unclear which ones can be deleted and which ones are in use.
2. Grouping of data sets by some criteria, for example, by connections or dashboards. When you have a lot of datasets, it becomes extremely difficult to manage them.
