That would be a great addition!

Anyway you can do that comparison highlighting? so you can tell what the differences are between the versions. Having 40 or 50 backup files in a folder will make it hard to tell what the changes were, and when they were made. And, if you revert back to an older file, how many recent changes will you lose.

Sometimes, just seeing what you changed will remind you enough to fix the problem, without having to revert to a previous version.
