By default, Simul shows you all changes made to a document compared to its previous version on the same branch.
You can however compare any two versions. Simply select the most recent document, in this example that will be version 0.1.0. Then "right click" or equivalent on the older version you wish to compare, in this example: 0.0.2.
Select "Compare with this version" and Simul will calculate the differences between the two versions and present this in the familiar format.
