No, not another whinge. On the contrary, I’ve noticed what I think is a new improvement. I could be wrong and maybe it has always been there, it is a long time since I last visited it, but I think this page [https://www.home-assistant.io/components/binary_sensor.template/] has been updated to include (wait for it!) links to relevant other pages.
This is a huge improvement and will be really helpful to new people, so well done to whoever updated it!
