• Tags now belong to you instead of to a list. The same tag works across every list, so in All tasks one tag filters your whole task list.
• A task you move to another list takes its tags along.
• In a shared list you both see the same tag name on a task. A name you don't have yourself shows without a colour; the plus button puts it in your own tags and gives it your colour.
• Renaming or deleting a tag also applies to the other member's tasks in a shared list. Before deleting you see how many tasks carry the tag and how many of those are shared.
• Managing tags works everywhere, including from All tasks.
• Through AI as well: list_tags and create_tag work on your own tags instead of one list's.
