I think / works well most cases, but is a bit annoying when you have several duplicate character sequences, so you end up having to type more and more of the sequence to discriminate.

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.
