At the moment, when a stealth / hacker character access a computer terminal, they pop out of stealth. Maybe this is because they are a one-finger-typist who needs to see their hands to type. Maybe it's because although there are Psi Mentors that can do neural imprinting, there's no neural interfacing to regular computer terminals. Maybe it's because all computer terminals require the user to hold still for a retinal scan before getting even basic access. Maybe it's just that computer use is mechanically implemented as dialogue and dialogue deactivates stealth.
Be that as it may, it would be cool to introduce a feat that allows the player to interact with a computer terminal while maintaining stealth.
Edit: changed threat topic only.
