T: switch UE in enb tracer
Just below the logo you see the current UE, eg. [UE 0], and near that you have two "buttons" [prev UE] and [next UE]. You click with left button of mouse on those and the various plots that depend on the UE are now done for the new UE (say UE 1 instead of UE 0 if you click on [next UE]). The plots are not cleared when you switch. Let's say it's a feature.
