Best way to view many classes

Hi,

More than a few times now I have played around with squeak. I keep leaving and recently I have realized why: I find it easier to follow code with in files than with a code browser. I can scroll a file fast and even I have 10 files open I still find it easer.

So my question is: what is the best way to follow and reference multiple classes in multiple packages? I know I could open more than one class browsers but that seems cumbersome.
