ELF: You can see in dim light as if it were daylight, but daylight doesn't do the old school night vision goggles blindness deal. A partial success to find a hidden door is treated as a full success. You live hundreds of years, it never really comes up and no one remembers so it doesn't affect anything. Dwarven bromance is an inevitability. If there is more than one elf in the group, they must slowly nod with respect each time they greet one another. It is the law.
