The data sources explorer pane gets crowded and difficult to navigate in large reports with lots of elements bound to their own data source.

Instead of the horizontal list of icons, I think it would be much better to have a table listing that can be sorted by clicking the column headers.

Data Sources should be listed in rows and Data Source Name and -Type should be in columns.
