I was thinking there should be some places you can (with some effort) set up to be able to safely store things, or be able to hide things.
Being able to use hacking/mechanics/electrition to fix the door in the cryofacility so that what ever you have stored there is safe would be a good exsample....
the sugestion of rented storage at DMC is another...
Being able to use like a shovel or a container and ropes to hide something making it verly unlikely to be found would be another nice option.
That way you can store things some where with out fear of scavangers comeing along and grabbing them.
Also Kinda think people shouldn't be able to walk up and take stuff from the area your in while your asleep if you have noise traps set up o.O
NPCs should in general be more carefull about trying to steal from some one unless there dying or unarmed if you ask me. Some guy laying there asleep with a shotgun straped to him I wouldn't want to run up bare handed and try and take the pile of food beside him!
