What I'm looking for is a function on a word processor that splits two documents on the screen. This is for revising and rewriting. I'm basically revamping what I previously wrote and it's a real pain in the ass to keep tabbing. Say I have my rough draft on the left side of the screen and what I'm revising is on the right side. I can look at the left side and type on the right in real time. I hope you guys know what I mean. If you do, then please help a brotha out. *Edit: Other than MS Word. (I don't have that) There should be some open source software capable of this but I can't find it.
