I would like to suggest a feature: a way to go to the next "What changed?".
Currently if I want to see what changed in every single wiki page edit, I have to click Next for both (left and right) revisions. It be easier and a lot faster to have one link to increase both.
Alternatively, if comparing revisions 7 and 8, incrementing the 7 could also increment the 8 automatically. Currently the user ends up comparing 8 to 8, but that does not ever make sense.
Do I make sense? :-)
