Hi all, Has anybody had a chance to check the draft document I made on Pad Stacks <https://docs.google.com/document/d/1lxBI7_X_I7pO-nuDHPRVlfRBH24XTmwuuN69o_Bqk3s/edit?usp=sharing> ?
I would like at least some feedback if this is the kind of document you would be looking for, or if not what to change about it/what it should focus on. I'm keen on pad stacks in KiCad since CADSTAR heavily relies on them - at the moment the importer wouldn't be able to handle complex cases. I would like to help wherever I can to get this in before v6 feature freeze. Thanks. Roberto.
