Built-in UI features (or lack of feature):

- for nonetlist components, the silk text is drawn in dark gray instead of 
black

- an internal footprint connection is not drawn in any way but is visible 
in text in the footprint pinout dialog; I think drawing such things on the 
desing would be messy, but I plan to do that on the footprint 
pinout/preview window

Indirect methods:

- internal connections are very easily found out when optimizing rats

- the default refdes for the 0-phm resistor footprint is J1 so when you 
place it from the PCB UI, it gets a J-number. I usually call my resistors 
R, so if I fail to notice the internal connection while routing and don't 
see the different color on silk text for nonetlist, I still notice the 
different letter. This is the only convention that's specific to the 0-ohm 
jumper resistor example; the other three are generic (e.g. in case you use 
a screw with nonetlist or specify intconn manually for a TACT button).

- normally I don't add resistors in PCB by copy/paste, especially not ones 
coming from the netlist, I let gsch2pcb do that for me; this is just a 
convention, but as long as I stick to it, it's impossible to mix nonetlist 
jumpers with netlisted resistors.
