It would be awesome to add some information about module parameters, like the impedance, voltage range, trigger width and so on, this would make it much easier to figure out which modules are compatible and which might need some tools like the aforementioned multiple or an offset/attenuator to make them work together smoothly.

Seconded. I keep a big ol' table with voltage ranges for my modules' ins and outs since they vary so much between manufacturers (e.g. Instruo Arbhar inputs expect +/-5v, Schlappi Nibbler gate outputs are binary 0 or 10v, Schlappi Nibbler stepped outputs are 0-10v, Modcan Quad LFO outputs are attenuable and can be either +/-5v or 0-10v, etc). Would be great to be able to fill this info in per input/output on the Grid.
