Allow to quickly see what matters in a diff #16
Description
In the diff view, I see the whole text and I have to scroll through all of it to find where something was changed.
Possible improvements:
- Support a compressed view which just shows the changes
- as above but with N lines of context
- Compressed view but show the current article as context (i.e. everything between two level 1 headings)
- Show whole text and add navigation buttons to move between diffs
