Gundo - Visualize your Vim Undo Tree

From the homepage:

“You know that Vim lets you undo changes like any text editor. What you might not know is that it doesn’t just keep a list of your changes — it keeps a goddamed tree of them.

Gundo is a plugin to make browsing this ridiculously powerful undo tree less painful.”

Definitely exceeded my expectations and is becoming one of my favorite plugins. Building in a diff view is genius.
