Tags, nested organization, and smart views

Folders are useful for location; tags now provide a second way to organize work by meaning.

What changed

• Create colored tags with one level of parent and child organization.
• Filter by any or all included tags.
• Exclude tags or focus only on untagged documents.
• Save useful filter combinations as smart views and pin the ones you use often.
• Add or remove tags from several selected documents at once.
• Rename, merge, recolor, and retire tags without rewriting document content.

Tags stay workspace-scoped and complement the existing folder tree.
