I have a repo up at https://github.com/cb22/immoral - but be warned, the code is nowhere even near alpha level. I'm still playing around with design choices, etc...

My normal Python coding skills are OK - but my knowledge of QT and QML is terrible, first time ever using them. Except horrible code in those areas

To all the ideas above - I'm keeping track, and once the base has gotten to a sufficent maturity, I'll probably start implementing things like GPG support, etc.
