Software to edit code in many vertical strips?

Question

I have a large monitor. I want to see a ton of code at the same time - instead of a single vertical scroll of code, I want lots and lots of narrow vertical columns of the same file shown side by side.A big use for this is code reviews, so even a non-editable view of text/PDF would be okay. Editable would be even better.I used to have some software back in the early 2000's, when Mac OS X was new that did a read only view in this way, but I can't remember the name.Any suggestions for me?

Slightly different but similar thing: SublimeText and a few other modern editors allow one to open multiple side by side views, which may allow you to achieve similar. Most of them can do this with distinct source files, but I know Sublime at least can do multiple views into the same file.

It almost sounds like you want a diff tool for code reviews, but I can't tell if you want an IDE instead (you mentioned edit code, after all).
