enhancement: during typeahead search, can we make it showing for example top 20 items?

[oopsmails]

I have a fairly long list of items, when doing typeahead search/filtering, I would like a feature to show top number of matched items, instead of scrolling down much.
More, if possible, maybe with a "More items matched ..." at the bottom.
