Currently, users have to climb up to Agile DB or Trackers then dive down to the wanted tracker/Kanban, which is cumbersome and get them a bit lost in the UI.
Admins have the "privilege" to be able to go to the tracker from the 'edit Kanban' modal.
Everyone should have an hyperlink at hand on the Kanban to the tracker report and vice-versa.

Moreover, since the quick(one line)-add artifact capability :
- is available only if the tracker has no mandatory field,
- requires immediate re-editing when you definitely WANT to submit with détails (incidentally polluting notified members in the process),
the "create new XXX" button should be present in the Kanban board header.
This is needed to really make the Agile Dashboard (or the Kanban widget on the Project Dashboard) the default entry point for non-Tuleap-specialist users.
