You can configure them from Window -> Order... -- it's clunky though, no doubt.
Drag and drop channels have been suggested AFAIK, and at one point they were on the table... not sure what happened.
As a note: please start new threads. New threads are free, and it makes it easier for users to find the right topic through search. Piling on questions in a single thread might be more convenient for you, but you should consider the other users who will eventually come here asking the same question.
