I'm looking at it being useful in a few ways.
1. It seems odd that a dip can stealthily take something, but then has to mechanically reveal themselves to put it away. Having a pocket command that doesn't break stealth, and uses similar stat checks to be noticed would be cool. Again, 'palm '
2. It could promote public transactions that might otherwise be done only in private, or add an element of measured caution to generally public transactions. Ex. Joe Baka has some drugs he wants moved, and he doesn't want his errand girl walking around with a target on her back. 'palm on .'
3. Street Magic. That is all.
Just some thoughts. What're yours?
