An integrated diff viewer for Pier is long overdue. The latest development version of Pier has a first implementation with a simple GUI. The implementation is not perfect, but it already starts to be quite useful for the engineering course here at the university.

You mean I’m going to have to merge new stuff into the pier2 repo?! :)
I guess so. I had to change and improve a few things in Pier in the last few days for this engineering course. I think that should be mostly easy to merge.
