I just found out about the awesomeness of Reddit Enhancement Suite. Is there any other Reddit scripts that make Reddit better?

I've always know about Greasemonkey scripts, but I never knew how to install Greasemonkey on my computer (I was probably just too lazy to figure it out). But after browsing through AskReddit, the Reddit Enhancement Suite website made it super easy, and now a whole world has opened up for me. Is there any other Reddit scripts that will help improve my Reddit experience?

While we're on the subject, is there any Greasemonkey scripts in general that will improve my internet experience?
