I think where this could save more time is if you thought about ways salespeople could close sales easier, since they require signatures so frequently.

If this product is just for me (i.e. the person who installs this extension) then it's only going to save me time. How often does the average Google Apps user need to sign something? And how often does a salesperson require a signature from somebody using Google Apps?

Just was thinking about where the real pain/problem exists here. And by that, I mean that it's important to consider where does the problem occur the most and have the most impact.
