Tags

Type tags separated by commas (e.g. "lecture, week 3"). The Tags tab shows each tag on its own row with how many documents it has ("#lecture · 4 documents"). Tap a tag to list only the documents with that tag; switch to another tag with the chips at the top, and the "All" chip or the back button returns to the tag list. On a document card, tags show as cobalt badges.

Signature view: at the top of the Tags tab there's a "Signature" row: Awaiting, Draft, Signed (with counts). Document menu (⋮) › PDF tools and signing › "Mark as awaiting signature" puts a document under Awaiting; "Save draft" on the Sign screen puts it under Draft; the signed copy lands under Signed with the "signed" tag, and the awaiting mark is removed from the source document. These three tags (awaiting signature, signature draft, signed) also go to your other devices via Drive.
