You need to be more flexible. Right now I have 5 categories. Pending, signed, declined, There should be one "completed". Also there should be an ability to file our documents in other folders that we can name. There also need to the ability to delete a signature.
For sure there needs to be a way to sort.
Take a look at Docusign if you want to see how it is done right,. Having said that Docusign is too expensive.
