I agree with Andrzej. This is the crux of my bug report.
But I understand what Jon is saying, and it doesn’t contradict. If the _pads_
(for example) are invisible, but say the silkscreen is visible, then the
footprint _should_ be selectable.
That, I think, is the difference between layer visibility and item visibility.
All of the layers could be visible, but if I disable Footprints Front, then
everything associated with all top-layer footprints vanishes and none of the
footprints can be selected. That’s the proper operation.
The converse of that is if I leave Footprints Front visibility enabled, and
then I go and disable all of the layers associated with front footprints, like
I did in my bug report case (disable all layers except Cmts.User), I am still
able to select all of the invisible footprints. That’s not correct (IMHO).
