When will password prompt be out for application association

Been tracking the progress of Espionage, well done on the new update. But my main purpose of using this app is for Mail App encryption.
With Espionage 3, I am still able to:
(1) Select Mail App, then encrypt it.
(2) Restart Mac (Reopen windows when logging back in... checkbox will remember the previous setting.. so my new default is off. No more conflict)
(3) BUT Upon Opening Mail App, it opens as if its brand new day 1. No password prompt saying the Mail App has been encrypted.
(4) I have to Close the Mail App now, and manually UNLOCK the Mail App by opening Espionage App and selecting it.
---When Will password prompt feature be coming back, its a simple feature that makes a whole difference? I really hope we can get a definitive answer before the 50% sale is gone...
