I am looking one of the use case to validating the history/previous value. Below is the use case:
I have two modules (Module1 and Module2). Both are copy of each other.
User will input the value in module1 and data will imported in module2 with the help of Import action. So ideally all the data of module1 and module2 will be exact same. Now if the data of module1 gets changed and then imported to module2, the changed data in a cell should get highlighted (may be with some colour).
Below is the screenshot once the data is imported from module1 to module2:
