Lazy highlight?

[wavexx]

Would be it be hard/possible to implement a slight delay before highlighting all matches in the visible buffer, as isearch does (see `isearch-lazy-highlight-initial-delay')?

This is not really for performance reasons (highlighting is fast enough), but mostly because the current match becomes instantly visible where there are many matches in the current buffer. I actually noticed I missed this setting from isearch after a couple of hours.

It seems a bit difficult but necessary feature.
phi-search(-core.el) code is, for now, not very clean nor smart and needs a mass renovation someday. So I'm thinking of implementing then.
