That's what 'n' is for. It also doesn't overwrite the 's' keybinding which is already used for substitution. I don't see the point of this plugin for people who are actually familiar with vim's keybindings.

I am aware of “n”. You can be familiar with vim’s keybindings and still appreciate a different way to solve a problem.

Something like Lightspeed lets you zone in on the specific character faster than repeatedly pressing n. Sure, that means installing a plugin, but some people accept that trade off.
