Thinking about giving the agent working the case a full picture of the client's issue/support experience with the support team, we should display the most recent cases that the contact or account on the case opened, if they fall into X amount of days (i.e: 1 week) of that case's created date.

This tells the agent if the client has had recent support interactions and what the issues were, so they can make a decision on if the issues could be related or even just about the best way/sentiment to approach the client on the new case.
