One quibble that I've had with 3.5's Search skill, and now Pathfinder's Perception skill is that a rogue is able to spot traps and secret doors from 10 feet away or more (depending on available lighting). I contend that an ingenious villain with access to talented craftsmen might hide some traps and doors from sight by hiding or disguising their mechanisms and seams, and these features would only be detectable if a thief senses them by touch (effectively requiring the thief to move within 5 feet of the target).
Therefore, as a minor change to this skill, I'd like to see an entry that adds detection of traps and secret doors by touch. Obviously, to detect by touch requires that the rogue be within armslength of the trap or secret door and should provide a DC bonus, possibly as much as +5 or more. Perhaps if the thief misses his Touch Perception DC roll by 10 or greater, then the trap might be set off?
This change would eliminate the arguments by my rogue players that ALL traps and secret doors can be detected at a range of 10 feet.
Hurm.
