I'm unsure whether my issue is the need for an additional feature, or a bug. Either way, a couple of days ago I posted a screen shot of my Design Manager Net List showing five S$ nets that I could not explain or find because they do not highlight. Whilst waiting for a reply I verified that they do not exist in the schematic, so I went searching on the PCB for random unconnected bits of track but found none. I then discovered that three of my mystery S$ nets were in fact BottomSolderMaskLayer "Tracks" that I had added in areas where current capacity needs enhancing. Of the two remaining, I found that one was a TopScreen "track" that I had drawn to show the outline of where a daughter board will be mounted, and hence where no tall components should be placed. The other I cannot find at all. If selecting an S$ net in Design Manager highlighted it in the same way as all other nets, finding them would not have taken many hours, and left the job unfinished - one S$ net still to find. Please consider adding the highlight feature to ALL nets in the design manager netlist. It would help immensely.
