I've unfortunately forgotten many of our older ideas; I'll post the worthwhile ones if and/or as they come back to me. Here's one I do remember, plus another I just came up with.
* The ability to control what anyone you can see can smell. This affects only the olfactory centers of the brain (or equivalent); for example, making someone smell chloroform won't knock them out, unless they they're especially susceptible to psychosomatic suggestion. It's not entirely useless because you could use it to prevent someone from smelling a dangerous gas that's filling the room.
* The ability to teleport your clothes to anywhere you've never been, without sending yourself with them. (Having teleported your clothes there before counts as having been there.) It's not entirely useless because, if nothing else, a time-delay explosive vest could be used to bomb an enemy base (or other desired target) from within.
