Page History: Ability to compare multiple versions and quickly see differences

We currently are on version 5.7 and working on upgrading to 6.3. What has been noted is that when a user makes multiple changes to the same document over the course of a day or more, it's difficult to see what has been changed so we'd like to propose some updates to Confluence if they don't already exist.

• On the Show History page, allow the user to see and select all changes by Date (all changes made today, last week, etc.) and/or by user.
• After selecting versions and clicking Compare, display a sidebar that allows the user to:
• > Display only the changes
• > Navigate to the changes

As an a side, when watching a page,I get an email that shows the entire document but no indication of what was changed. It would be helpful if you could highlight the changed text.
