For the amount of money being charged for this application, it seems such a simple request to be able to password protect the application on the computer. It is worse than trying to locate the last Easter egg. If one can use ONE password to retract access to the master app on the computer that would be wonderful. However, in the absence of such a simple arcane request, perhaps some enterprising software developer should generate a synchronizing note app WITH a password and then we can all move on pass Nevernote. Unbelievable the apparent arrogance of ignoring such a simple, basic but necessary request.
