WANT TO LOCK K-9 ??  TRY EMAIL LOCK....... available on Play store....... Its crazy that this feature is not already standard on a mobile email client! ! There isn't much not to like about this email client and it has worked flawlessly on test. But the only feature that is missing is access protection. I can't believe anyone could develop such a great client and miss out such an important security feature for a mobile device. I really don't want my email available to just anyone who picks up my phone. I am calling on the dev to add a password on start   or for another developer to make a plugin to add this missing important feature to K9 mail.
