A different software tool I have used had a function where you could select an entire net in the PCB and it would highlight that track and suppress everything else into a "shadow mode" view where everything not selected was grayed out. Is there anything like this in Pulsonix?
If you use the Find bar click (o) for options and under 'Find'- 'Action on found item' you can highlight it, brighten it (dim all other items) flash it etc. You can use Shift + click to select a track segment and (h)to highlight a net. There are also options in Options - Display - PCB Drawing - Highlight tracks using a stripe which also might help.
