KB Compare - ServiceNow Version Comparison Script

A Tampermonkey script for ServiceNow that allows you to compare different versions of Knowledge Base (KB) articles in a GitHub-style unified diff format. This script helps knowledge analysts easily visualize the differences between article versions, with collapsible sections for unchanged content and proper version, author, and date extraction.

Features

Version Comparison: Compare any two versions of a KB article/block, showing differences using a line-by-line unified diff.
Author and Date Information: Each version in the dropdown is displayed with the correct version number, author, and date.
Collapsible Unchanged Lines: Unchanged sections of the article can be collapsed and expanded for a cleaner comparison view.
GitHub-Style Diff: Changes are shown in a unified format with green for additions and red for removals, similar to GitHub's diff display.
