The ProjectFeaturesTab uses ArrowUp/ArrowDown icon buttons for reordering features. This is tedious to use when a queue has 10+ items. The UX instruction banner even shows a GripVertical icon (suggesting drag-and-drop intent), but drag is not implemented — creating a confusing expectation gap.
Category: usability File: src/components/project-features-tab.tsx Recommendation: Implement drag-and-drop reordering using @dnd-kit/sortable (already a common pairing with this stack). Show the GripVertical handle only on draggable items. Retain the up/down buttons as a keyboard-accessible fallback but de-emphasise them visually. Remove the GripVertical icon from the instruction banner if drag isn't implemented to avoid false affordance.
