3. Hide Unwanted Datasets

Hide datasets created in personal spaces, or for testing purposes which aren't relevant to the entire company.
Click the name of your database in the left sidebar to see all the schemas and tables in your data warehouse.
Use Cmd/Ctrl+F to open a filter where you can search for specific datasets to remove, or use the filters in the right sidebar to show items with the lowest popularity.
This can help identify un-used datasets or datasets only used for testing purposes.
Select the datasets you'd like to hide (Use Shift on your keyboard to select consecutive items) and click the Hide button.
You'll be prompted to confirm before deleting.
You'll be able to add the data back if you need to later. See this page on managing data sources for more information.
