Since dispname can be use to display a modified
headline for the issues listed it should be usable from
home.html.

For this it is necessary that renderWith() can take
dispname as optional argument. The following should
become possible:

<span tal:replace="structure 
  python:db.issue.renderWith('index',
    sort=('-', 'activity'), group=('+', 'priority'), 
    filter=['status', 'assignedto'],
    columns=['id', 'duedate', 'title', 'assignedto',
             'creator', 'project','activity', 'status'],
    filterspec={'status':['-1', '1', '2', '3', '4', '5'],
                'assignedto':request.user.id},
    dispname='Your%20Open%20Issues')"/>
