Activateable ListBox item discoverability issues
I have had complaints from different people that the ListBox items (in the display panel) are not discoverable as items that can be modified by the user. i.e. the plain label + data looks more like it simply displays information rather than allows interaction.
It might be good to add some sort of further indicator that these elements can be activated. As an example, a three dot "menu" at the side might solve the interaction issue.
