So I was forced to upgrade to a newer version of an email client that i was using - the newest version sucks. A friend and I had recently talked about how the future of OpenSource could simply be a set of prompts that you feed into the agent of your choosing to generate the application. This is that experiment.
The app (that we're calling "Shifted") puts all of your gmail accounts into a single window, preserving the Gmail web interface. It supports Calendar as well.
