When the feature table is open, the user can switch to Show Selected Records to see only the selected records (in blue by default). In this mode the user can highlight (in yellow by default) a sub-selection by clicking on the far left side of the record. Those features are then also highlighted (in yellow) in the data view.
I would like to see an enhancement where the user can also make this sub-selection by clicking on a selected feature in the data view to highlight the feature in yellow, which in turn will highlight (in yellow) the record in the table. Maybe this could be added in the right-click context menu?
