Suggestion: Double click a historical entry to view diff (perhaps using a 3rd party tool?)

There's already diff integration with 3rd party tools, however I noticed I can't use it for anything historical. For a real example:




1. I added an ability, "Shock".
2. Our dev that usually works on abilities pushed a fix for "Shock" with comments.
3. A few days later removed the comments.
4. I only just jumped back into Unity, missing a few days, and now I can never see those comments again unless I revert my entire project (rather than a diff preview) -

This is not ideal, and where my suggestion comes in:

Would be great to double click a historical collab file to show a diff of changes and even a preview when dropped down, like for example what GitHub does:
