Ability to see  related / original conversation information if  I've been assigned a specific message from the conversation as a task.

For the time being managing this from the priority inbox isn't really feasible because of the time it can take to locate the specific message (since it's a task I was assigned, I only know the username.) As an example: I spent 5-10 minutes trying to find the exact conversation on several occasions today. That's sort of messing around doesn't work at scale.
