Regarding bedroom light switching, in the home of a relative I oncle installed a Columbus time lag switch in parralel with and adjacent to the normal light switch.
This allowed the ceiling light to remain on for long enough to walk across the room and get into bed. I rejected the more usual approach of two way switching with a pull cord over the bed due to lack of access to fit same.
And the Columbus time switch, if pneumatic, woke the room occupant up after a few minutes with a loud "CLUNK" to remind him that he was just sleeping and not permanently expired.
