I'm never bothered by iTerm2 being too slow or using too much CPU. Using transparency for my tmux profile makes it easier to tell whether the tab I've switched to is a local or remote session. Seeing coding ligatures makes me happy. Why is the thing I don't notice objectively more important than my convenience and happiness?
