Not sure if anyone has mentioned this, I have done a quick search but couldn't see anything.
Anyway in the light lister when I select a light using the checkbox in the light lister dialogue, it adds the light to the current selection if something is already selected in the viewport i.e. a wall or a sofa. It would be good if it would clear the selection first and then select the light so the properties for the light appear in the modify panel.
At the minute I have to make sure nothing is selected in the viewport before selecting a light in light lister.
Whilst most of the properties are available in the lister itself, some still require going to the modify panel such as selecting an IES profile or include/exclude
