So I'd prefer either: - built-in elements that cover common elements like autocompletes or typeahead elements that allow e.g. the inclusion of images and formatting with their suggestions, or - custom elements to work well enough in practice that those elements would have been created by third parties and would be widely used now. I don't know whether the latter is actually possible, but I'm lamenting the fact that a focus on that goal seems to have coincided with hardly any attention being given to the former.
