Basically, my question is twofold:
1) Does the Trapfinding rogue ability grant its bonus to Disable Device checks in general (disarm traps, open locks, etc) or only to Disable Device checks made to disarm traps?
2) What type of bonus is it? Competence, circumstance, racial, etc?
1. The ability specifically mention only working when looking for traps with perception, but doesn't make such a statement with Disable Device... so we have been playing it all DD checks.
2. since no bonus type is given we have been treating as an untyped bonus (stacks with everything).
