It provides high-value "peace of mind" for a tool that is often used for quick, messy drafting where mistakes are common.
A list in the sidebar (e.g., "Today, 8:41 AM") showing when changes were made.
When clicking a previous version, the app highlights what was added (green) or removed (red) compared to the current version.
Instead of just saving the current state, this feature tracks changes automatically, ensuring no data is lost to accidental deletions or "save-overs."
A "Revert to this version" button that instantly replaces the current text with the historical data.
Even if the user isn't logged in, the app saves the last 10 versions to the browser's local cache so they survive a tab crash.
