The idea is to extend the options of a backoffice operator when managing contents, adding "unpublish" and "delete" content buttons in the edit view, where standard "save" and "publish" buttons are present. I am adding shapes to the referenced driver, shapes are going to be very similar to the ones already present in the "Core/Contents/Views" folder (e.g. "Content.PublishButton.cshtml") Controller actions will be inspired by already existing unpublish and remove actions in AdminController.
On top of that, a little adjustment to the Placement.info is likely going to be needed.
