- Relation/kind/intent should be placed on the bottom of the popup, next to the Add button. We should make quite clear, that the relation is applied to the selected assignment, and it is not used to filter the selection. Controls that filter the seleciton should be at the top, controls that influence how the assignment is created should be at the bottom.
- If no checkbox is selected the Add button should be disabled - or click on that should result in an error inside the popup. But the popup should not be closed.
- (Maybe) clicking on the name in the table should immediately close the popup - this means selecting a single target. Click on the checkbox means we want to select several targets. If any checkbox is selected then click on the title should not work (to avoid accidentally ruining my checkbox selection)
