I understand that removing terms from the functions/secondary functions dropdown list is a delicate matter. In fact, I personally don't think it's already too long at all, and while a bit of clean up seems like it could be helpful, I was mostly just interested in adding a few. But I get it: the admins at ModularGrid want to act parsimoniously.
So, I guess if I had to prioritize, I'd keep my request to just add "analog" to complement and contrast with the existing "digital" option. For the time being, anyway.
