Frist, the program works and does what it should do, you can encrypt and decrypt emails with it (5 Stars for this). But for this steep price I would expect 2 more features which should make the users life easier (minus 2 stars). 1. Multipart Mime support Email are usually multipart mime encoded, so decoding all parts and offering separate handling for this (think file attachments) is a must. Also Id like to add files I want to encrypt (from Goodread for example, or even better dropbox support), this also implies multipart mime support for composing (email) messages. 2. Why encrypt and decrypt in 2 separate views? One view, two buttons makes more sense here.
