thank you for your suggestion!
We already have an open feature request to add auto-crypt support and I've added your comments and vote to it. The number of votes is one factor that helps us to determine what feature to add next.
This discussion will be updated however, when the requested feature is available.
The problem with that is, that encrypted messages are currently only searchable by subject. Adding auto-crypt would result in all OpenPGP messages being unsearchable. We are still looking for a solution to that problem.
