Use case or problem
One of the key use cases for a version history is to see how one or more lines have changed over time.
A simple example use case is to find out when a particular task item was checked-off.
Proposed solution
The solution is to have a feature similar to git log: one or more selected lines may be selected, and through the context menu, view the history of those selected lines.
Current workaround (optional)
There is no real workaround other than to manually dig through the sync history.

The history will only be as useful as what was recorded, per: Obsidian Sync: Sync upon change to a block instead of a few keystrokes - Feature requests - Obsidian Forum
