A view like this would really be beneficial.
Maybe as a filter for the Dashboard, or better, directly at the electronic Signature (at least as a filter “my docs” or so).
 
Because as a user, I want to get a view at a glance, what is still open for signing by me, without searching the System.
 
In General, it is difficult to find out the Status of the Routing process of a document (except in the preview). Maybe this still can be optimized.
