**Acceptance criteria**

* Clicking on "Team planner" in the project sidebar drills into the "Team planner" sub-menu.
* The first item is a back button with the title "Team planner"
* In this sub-menu, there are four possible headers in the sidebars:
* "Favorite team planners" visible only if there are team planners that have been favourited
* "Public team planners" lists all saved team planners that are public
* "Private team planners" lists all team planners that are marked as not public
* The "Create team planner" only ever has on item (New team planner)
* Within each view, the list of team planners is arranged alphabetically, allowing users to also prepend numbers to govern this
* To navigate to other saved planners, the user has to pick a different planner from the sidebar. Begin of the insertion

**Out of scope since persisting team planner is possible**

End of the insertion Begin of the deletion
End of the deletion * The last header "Create new planner" has only one item, "New team planner". This is essentially the "Create" function (now that we don't have an index/list view for this v1).
