Other people's ___

Often enough we look at other people's ___ (fill in the blank here) and say wow, but more often than not when we actually get to lay our hands on it, we find it less than impressive or even super annoying, and end up having nothing to say but meh. For Zsh geeks, examples include other people's Zsh prompts, zsh-syntax-highlighting, and zsh-autosuggestions.
