The website editor now correctly shows the autocomplete search bar in the edit menu, making it easier for users to find and link to pages or routes while editing. Link searches also cover all matching website route records rather than only the first one, improving search accuracy.

Project users can now choose any task as a parent task, making task organization more flexible. Subtasks are shown more consistently across tasks, while the subtask project setting remains managed at the project level.
