The "Document Difference Viewer" that displays when comparing article versions could use some improvements. Currently, I have to copy and paste each version into a third-party editor to properly compare versions.

The red that is used to highlight changes does not have sufficient contrast for WCAG certification.

For the "Code diff" section, when comparing pages made using the Markdown editor, it would be nice to display the text of each version in numbered lines (like in github, vscode, etc.) to make comparing between versions easier.

Other UI improvements that could significantly improve the UX would be navigation that allows you to easily scroll between each difference ("Next difference ->", "<- previous difference", etc.), a search bar, and a toggle that allows you to scroll both versions at the same time (instead of independently)

Thanks!
