For a build that is sitting in the queue that was started by a user clicking the build button, it would be tremendously helpful to see the users name when I hover my mouse over that job in the queue. I envision something like what parameterized builds do (we see the parameter values when hovering over the job).

For those builds initiated by an SCM commit(s), displaying the user(s) that committed the change that initiated the job would be very helpful.

For those builds initiated by a timer, maybe "Initiated by timer" could be displayed.

We'd want this information to help us to know who to contact if we need to re-prioritize or cancel jobs sitting in the queue.

Since we use the build-user-vars plugin, we'd be happy if someone from this team implemented the functionality as well.
