With the current Auto Quick Answer toggle it only provides the ability to use a ? in the query string, but for more ley users who are not "programmer centric" or "techie", it would be helpful to provide them an option to always run the Auto Quick Answer and not have to enter the ? in the query. Funtionally, it would be automatically expanding the quick answer feature in the UI which eliminates the click to open it when the search is completed. This might be more intuitivly acheivable by providing a check box in the quick answer UI on the search results page.
This should not effect existing users much as it would be off by default.
Users who are not as technical as someone who would think about typing a ? to access the auto quick answer are always having to open the quick answer which increases the cognative friction of using the search engine for a vast majorety of the users in the world for those who enjoy using AI quick answer type of features on Google and DDG.
