Oh, that's awesome idea! If it uses IMAP4 variant under the hood and not completely different/proprietary API - are there any plans of possibly releasing this

Oh, that's awesome idea! If it uses IMAP4 variant under the hood and not completely different/proprietary API - are there any plans of possibly releasing this as a standalone tool someday? I don't use Protonmail, because I already have self-hosted own-premises mail system for a long while, but I don't have encryption at rest. Given that you use OpenPGP, this bridge app looks very interesting. If it only could talk to a local gpg-agent as an option (rather than an PM account), it would be probably just perfect.
