When looking for other stack-exchange site, I usually use the Super collider drop downs menu search bar.
I would expect to be able to expand the menu and be able to type immediately the name of another site.
Could we automatically select the research field when the menu is clicked? Eventually, auto-scrolling to show the result would be great as well.
Edit: As stated by yo', the case of 7+ site in the menu should not be neglected. We do not want to scroll automatically if it masked the "favorite" sites. Maybe it could be triggered on key press only?
