We have an option to view Word document
As we view the document we want to add annotations, notes, comments, issue, assign a task etc.....
The viewer does not allow us to perform those task.
In addition, if we open a more recent version in the viewer, we should be able to open on the side a previous version for consultation and ultimately compare two version.
The compare version should allow us to compare more than one version and be able to see a timeline of the changes
