// The Dock's pinned applications: reorder, remove, and add.
//
// The list was a sixteen-entry literal in Settings.qml, so changing what sits
// in the Dock meant editing a QML file and reloading the shell. It is a plain
// ordered list of desktop entry ids, stored in the shared settings file, which
// means it is covered by Restore defaults like everything else.
//
// Move up / move down rather than drag-and-drop. Dragging inside a Flickable
// that is itself inside a scrolling page is a genuinely hard interaction to get
// right, and it fails in a way the user reads as the app being broken; two
// buttons are unambiguous and keyboard-reachable.
