I think that the workflow index(../workflows) could be more useful made like that:
a drop down on the top, to choose the tracker, and then a grid showing on the x and y axis all the statuses (on the y-axis the "from" status, and on the x-axis the "to" status), and in the grid, in every cell, the list of the roles that have permission to change the status from that "from" to that "to" status.

In addition, every role can be a link to the page of editing.

This way it is possible to have a real overview of the workflow on every tracker, information that is not available easily at the moment
