I'm the first person to suggest this? I'd expect that the ultimate goal of this plugin is to make GPG work without me even noticing : I enter my pass phrase when I start an email session, and after that I only send/receive email without ever wanting to see PGP encoded emails again - it should be done in the background and only notifying me that emails are secure. I've switched to the Eudora (Penelope) + Enigmail combo now which works flawless.
I'm sorry if this sounded rude - that's not intended. I understand you're programming all this for free and in your spare time and I'd never be able to program anything like this. I'm trying to say what I currently don't like about this extension.
