When I develop tools/real products for others, I try to come up with the best defaults and provide the best experience out of the box, because most people don't ever touch settings. On the other hand, I think it is important to have almost as many settings as technical possible/feasible and try to make them discoverable, and encourage people to customize -- although maybe not spend too much time on that.

One setting that completely changed how I use vim: relative line number (and the "smart" version). I learned about it recently and realized I had wasted a stupid amount of time in the past decade since I used vim. Should that be the default? Probably not. But people do need to customize the editor to make it the most efficient and productive for themselves. I just wish relative line numbers are marketed more, and there is a way to gradually discover settings that people may want to tweak.
