I understand that wallet backup is simply a matter of copying the wallet file to a backup media & then (if necessary) copying it back to restore it. This also makes it easy to transfer my wallet from one computer to another if I buy a new one.
I am concerned, however, that if I have a visitor who has physical access to my computer whilst I am otherwise occupied, they could easily & quickly take a copy of my wallet & then go home & spend my bitcoins.
Am I correct n this scenario?
Is there any intention to make backup easier for the average computer user - ie a "backup" button on the client? Having a password on the client program, which would also be needed to initiate a backup or restore, would solve this security flaw.
