The documents you sent and the documents someone sent you are different jobs. One is work you are waiting on. The other is work that is waiting on you.
A list shows the documents that still need your signature. It is separate from the ones you sent. Open it when you need to sign, and you are not looking through envelopes that are sitting with other people.
Tabs only appear when there is something in them. An empty list does not take a place on the dashboard. When a document is waiting on your signature, it is in that list until you sign it or the request is no longer yours.
