I can't find documents I've imported to Paperless. Where are they?
All documents imported to Paperless (regardless of how they are imported) are imported directly to Everything in the sidebar.
Paperless maintains a smart collection called the Inbox, which shows all documents recently imported to your library. Any newly-imported document should appear in your Inbox, as well as in your Library.
Items can be removed from the inbox either manually or (if specific actions are performed on a document) automatically.
For more information on the Inbox and how Paperless handles documents in the Inbox, see this knowledge base article.
