Highlight only the trace of the selected anchor

[GGard]

Hello,

While working with Predictive models, I got confronted with this situation: 

The highlighted traces are linked to the box even though you click on an anchor.

It'd be much simpler to trace this spaghetti if, when we select an anchor, only what is connected to it stay highlighted.

IDEA: Click on the box, keep all output visible in blue, click on an anchor, anchor's output is visible in blue, the rest remains in black.

Like this:
