[minor feature] Trigger search by double-clicking "related searches" item?

Hi, I like the "related searches" pane a lot - it saves lots of typing sometimes. Now I wonder if it wasn't useful to just double-click one of the searches and then initiate it? Currently it's only written in the search bar and you have to trigger it manually by "Search". However...as the subject says: MINOR. Just put it on your to-do-list, and I won't complain if you put it on the bottom for now. It would simply be a nice-to-have. Thanks for considering. :)
