Appreciate the feedback. We have a lot more signing options on HelloSign.com. For example, you can create a signature on HelloSign.com by:
1. Using your smartphone
2. Uploading a signature image
3. Typing it in
4. Drawing it in
For V1 of the Google Docs integration, we only added the draw it in option for Docs Add-ons. The other types are coming. Either way, if you want to upload a signature, you can still do it on our website and it’ll show up in Google Docs as saved.
Preview is useful, but there are a few reasons people still use us:
1. We’re closer to the documents than Preview
- You can sign directly in Google Docs, Gmail (https://www.hellosign.com/gmail), Google Apps, and elsewhere.
2. We do signature work flows.
- You can request signatures, cc key parties (like a cofounder or lawyer) and other business functionality.
3. We’re cloud based
- You can use us anywhere.
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.
