I don't need a better shell, I need a better terminal. On Mac we have Terminal.app which is nice and fast but the feature set is limited and notably doesn't support full color. On the other hand we have iTerm 2 which has too many features (creeping featurism) and is completely ass slow and most annoyingly has high latency. It also leaks memory like it's going out of fashion. Running neovim on fish on iTerm 2 is just an utter pain.
