A manager controls output to tty and cannot be be shared between track.Readers. I think that's why the unit tests are failing.

It's not right to merge managedReader into NewReader. I would suggest to move it to target.go.

Manager should be the only way to access tty, trackable readers or targets should not access tty directly.
