The feature he's saying is that mac os preview allows you to take a picture of a piece of paper with your signature on, and then places that in the pdf. You should implement this - or at least try it. There's no dragging mouse that will be ever be close to how natural this feels.

Disclosure: I'm a happy HelloSign user.

This is what HelloSign has done since the beginning. Take a picture with your phone, send the signature in, and you can attach it to most anything. It sounds like it's not directly exposed in the Google docs addon, but you can still jump to the full app to do it.

Does it work the same as Preview? Preview actually detects my signature on the page I'm holding up and creates a vectorized version of it automatically. It's not just a photo.
