Currently the software is not asking any questions before performing any sort of transaction.
So it's really easy for people to send all the BTC's to some random bitcoin address in a few seconds the owner steps away from the computer without locking it.
I know that it is more of an issue of local security and trust, rather then a software problem. However for majority of non-technical, non security-savvy people some safe-guard should be in place.
Maybe even combined with wallet encryption.
What does everyone think about it?
