I also like this idea, conceptually, but would need to see how much this would take away from running the core ProtonMail service before championing it. Like someone noted below, clients like Thunderbird are going independent and might be open to working on something.Two features I have always wanted to see in a mainstream email client are (1) ability to lock/encrypt the database stored on the local machine until the user unlocks the app with a separate password or other form of authentication. Also (2) integrate PGP/GPG and other message encryption mechanisms into the core product, rather than rely on the third-parties for add-ons.
