I have used Vim for sometime now and I love the split window feature where you can see all pertinent code all at the same time. I am using eclipse because it is making my life even easier. I just found out that you can split windows in eclipse too. All you have to do is open the files. Eclipse will open them in tabs as usual. Then drag one of the tabs to the side you want until you see an arrow, then let go and viola. I am using Eclipse 3.4. I don’t know if this works in all eclipse versions.

Edit: Here is a video to demonstrate:
