Library layout and document cards
Android · iPhone · quillo.trUpdated:
The tabs sit in a dark capsule: All, My documents, Folders, Tags. On the All tab your folders are a single row of chips at the top (pinned first, then recently used; "All · N" opens them all), and "+ New" creates a folder. My documents lists every document (it can be filtered by type); Folders holds the whole archive (search, sorting, pinned); Tags first groups your tags with their document counts, and tapping a tag shows only that tag's documents.
Each document card has a 3:4 cover (tinted by type, with a thumbnail of the first page), a progress ring at the top right (the percentage read; a tick when finished), a turquoise play button at the bottom left (continues listening from that document), and below it the name, type and page ("PDF · 12 / 40" or "Read"), cobalt tags if there are any, and ⋮ (More) on the right. Favourites are marked with a star.
The "Where you left off" card shows the document you opened last: a small cover, the "WHERE YOU LEFT OFF" label, the document name, "PDF · Page 4 / 12" and a large turquoise play button on the right, with wave lines, a progress line and the percentage at the bottom. Tap the card to open the document, the play button to continue listening, or press and hold for the document menu.
If you have study cards due today, a line such as "3 study cards to review today" appears in the library.
