The 'strange' component choice (and the mix of THT and SMD one) is because it's designed to be built with the component I have at hand in the workshop at work I.E. a >10A mosfet is NOT the usual choice driving a 3-4A load:D:D

Since they are connected anyway i devised the funny symbol you can seein the upper left. The two nets can be then routed correctly and the symbol is a 'virtual' module with a 'graphic' line on the copper plane to give the connection AND pass ERC. This way you could also pass a power ground trace inside a signal ground zone fill keeping them separate. It isn't done here but in another job I did so. And it works great (having a 30A load and athermocouple amplifier on the same board has 'some' ground issues :D)

Confirmed that for this schematic, netlisting stops working properly some time between R2005 and R2046. Note that, as I posted earlier, to test with this schematic, you have to massage the .pro library entries a bit, becausethe custom libraries which were used are not directly included.

On a related note -- the demos subdirectory is great for regression testing, but it could use more examples. I would assume the demos don't all have to be under the same license as the main package, so perhaps the developerscould add this example to the demos under Lorenzo's license, and create a policy for accepting more demos.
