Novice questions

I studied electronics years ago but have never worked professionally in that industry (I’m a software engineer by profession) but have often dabbled in electronics as a hobby since then.

I’m new to simulators and QSPICE so I am going to be asking very basic questions so please be kind!

First, once I’ve got a circuit and an analysis done and I can see voltages plotted, is there a way to remove a trace from the graph?

So for example how would I remove the green plot above? Do I need to visit the schematic and somehow find where I put that and remove it from the schematic or is there a way to simply mask the visibility of a trace without doing anything to the schematic itself?

Click on trace then press delete.

Best regards

Somewhat related scenario is if you have multiple windows, you can click and drag waveforms between windows.
