| parents | magsign_widget |
| remarks | borrowed terminology from DOM? |

| magsign_add_inputs | |
| content | adding 3 inputs to the module using =addInput()=. |

| parents | magsign_process_inner_loop |
| file reference | codestudy/potential/mag_sign.cpp:25-26 |
| only_first_inputs_outputs | |
| content | Only the first inputs and outputs it seems. In C++, it's at array index 0. I'm guessing that this plugin has only one channel in and one channel out? and this is stored in the first input. |
| tags | inputs[0], point, clarify, what, and, outputs[0], to |
| call_mag_sign_process_raw | |
