Any well respected DIY handy man knows about the tool range WORX. If not bow your head in shame now. WORX release version two of their handy SD driver and it now comes with a handy screw holder. As simple as it sounds, the practicality of this is beyond reasoning. This will ease that hard to reach places where you can now use only one hand and steady yourself better with the other. It will also clamp on automatically to any screw during an unscrewing process so you would never have to search again for a dropped screw. Other features include a built in LED light for those dark corners and it is powered by a lithium-ion battery that does not self-discharge.
