Multipage HTML Output
It would be amazing if there was a way to output multiple (linked) pages of html diff data. In my case we're diffing some large xml files and have 2 current easy options: Make one html output file with a small percentage of the diff, or make a huge html file with the whole diff.
The problem we run into with the giant diff is that it's so big that Chrome (and other browsers) have trouble rendering / searching properly. Optimally there would be a way to get the first bit of diff, and expand / move to next pages of diff as you go.
