While I welome the idea of the more searches feature on the drop down menu, and think that is a helpful addition. more often than not I want to repeat the previous search and it is a bit of a pain going to the search line in the drop down menu and then not knowing whether you will have to go left or right!
Could there not be "repeat search" on the drop down menu, and under it "More searches".

I hope you know what I mean as I don't have Beta running right now and so I may have got the wording wrong.
