This is not referring to the tasklist macro but the possibility of introducing tasks as a first-class citizen in Confluence. See suggestion from Tim below:

Suggestion: Action Item overview (tasklist item overview) in dashboard
The idea is to have an additional tab in the dashboard of each of our employees, where either:

• all action items
• only action items of a particular space
  created via dynamic tasklist are summarized and shown

The action items should be shown in a table (searchable, filterable/hideable and sortable).
Table-Fields:

• status
• Priority
• additional responsibles (besides me),
• when created
• deadline
• topic (maybe via the name of the sub-page and dirct link to it)

Benefit: I as a user do not have to search for all my action items on 1mio wiki pages, but have them all in one table (searchable, filterable and sortable).
