I think that checkbox "Only show illuminated elements" doesn't work.
When checked it still showing not flaring elements (with [ - ] in name).
version 1.3 web-start
The option "Only show illuminated elements" does not filter the elements depending on their name, but on their illumination status which appears in the results. Illumination is 100% when the element is lit by the sun and less if it is located in either earth's penumbra (< 100%) or in earth's shadow (0 %).
