I like how the "Symbology" pane pops up when I click on a layer's symbology. Similarly, I would love for the "Element" pane to pop up when I click on a legend element. What else am I going to need but the element pane? Sometimes I need to switch back and forth between legend and symbology in order to manipulate legend patches etc, and it would be very convenient if the "Element" pane just appeared same as the "Symbology" one.
