The name Rhodes chose isn't the name you'd look for.

The quickest way is to ask. "Rename that to Bramble Hollow — 2024 Operating Agreement" or "file the 2024 K-1 from Northgate Ventures II under Fenwick Trust instead" both work, and chat will show you the change before making it. This is also the only way to fix several documents in one go.
If you'd rather do it on the page:
Rename — click the document's row to open it, click the pencil next to its name, type, and press Enter or Save. Escape or Cancel leaves it unchanged.
Delete — open the row and click Delete, then confirm. Deleting also removes the document from Home → Needs you. This requires admin or owner; members won't see it. Members who ask chat to archive a document are told to ask an admin.
