I'm using Acrobat X pro for Windows. I found that two lines of tool bar takes too much space. So I would like to combine them into one line, or move them to left or right side. I do know that I can hide those tool bars by Ctrl+H. But I want to use them without hiding. Since most documents I use are letter size and portrait type, tool bars on the left or right side would be much more efficient way of using space. Does anybody know how I can do this?

(I think I could do it in Acrobat 9..but I can't in X version)
