I'm building up a small AVR dev board in tscircuit, and I've reached the point where fitting an ATmega328P, CH340G, USB-C, regulator, headers, crystals, and mounting holes on a 45×18 mm board causes lots of placement/courtyard conflicts. At this point, is it better to increase the board size, or is there a layout approach you'd recommend?

Also, while building it I noticed that if I use pin names like `D+`, `D-`, `UD+`, or `UD-`, the build succeeds but those pins seem to be silently dropped from the component, so the connections don't get created. The only indication is a warning in the logs. Is that expected behavior?

that is basically the intended behavior

it is always good to visually represent errors on the pcb if possible but it is expected to be a warning- it isn't silently dropped because there is a warning
