**As** a project portfolio manager
**I want to** see the dates of stages/gates in a consolidated view
**so that** it is easier to understand the state and progress of a set of projects.

Assumes ###58159 is done.

**Acceptance criteria**

* Every gate/stage can be added as a column to the project list.

* Those are selectable using the already existing means: The modal for "configure view" and the setting for the default columns in the administration.

* The autocompleters and column ordering component do not show the colored prefix (see below).

* This means stages/gates can be added out of order. This is accepted. Begin of the insertion

* The value is not displayed in case the stage/gate is disabled in the project (##58163)End of the insertion

* Adding new stages/gates (###58161) does not add the columns as default columns.

* Begin of the deletion \[open\] Is there a new default list?

* \[open\] Is a list seeded?

* End of the deletion The column header for stages/gates has a type indicator.

* It is rhombus shaped for gates

* It is arrow shaped for gates

* The prefix is in the color configured for the stage/gate.

* Begin of the insertionIf aEnd of the insertion Begin of the deletion The projects can be ordered by theEnd of the deletion stage/gate Begin of the insertioncolumnEnd of the insertion Begin of the deletion column. For stages, the start dateEnd of the deletion is Begin of the insertionsavedEnd of the insertion Begin of the deletion the primary, the end date the secondary comparison attribute.

* \[open\] How are empty values sorted?

* \[open\] Should there be filters for each gate/stage defined? That would enable querying for e.g.

* "Projects which are currentlyEnd of the deletion in Begin of the deletion the initiation phase"

* "Projects which's kick-off is in 5 days"

* Because of the structure the filters are currently in, we would need to haveEnd of the deletion a Begin of the insertionlist, that list still works ifEnd of the insertion Begin of the deletion filter per gate/stage and cannot includeEnd of the deletion the Begin of the deletion selection of the phase as a value with maybe the only exception being the one for the currently active phase.

* In case aEnd of the deletion stage/gate is Begin of the insertiondeleted inEnd of the insertion Begin of the deletion disabled,End of the deletion the Begin of the insertionadministration.

End of the insertion Begin of the deletion project is not matching the filter (see ###58163)

End of the deletion * The new functionality is hidden behind the feature flag developed as part of ###58159
