I'd like to have a portable version that I can keep on a USB drive so no need to install on the computer. I would also like to be able to sync across my computers by moving a USB from one computer to another. Those of us who are paranoid about unknown security risks in the cloud, or even across a WiFi network, would prefer to keep the program and sync within a USB drive in our hands. The program on USB could communicate (if necessary) with the developer when first installed, but should not communicate after password data has been entered into the program.
