Is your feature request related to a problem? Please describe.
When using collectives with multiple users (especially in a company and political party) it is often necessary to understand changes in wiki pages. Collectives provides a a side-to-side diffing, but no highlighting of the changes itself, that is very essential - especially for larger pages.
Describe the solution you'd like
Visually highlight the changes in the diff mode on line and character level.
