Open a PDF that lives in your graph's assets/ (or drop one in). On desktop it opens as a normal tab in a companion pane, keeping the page you came from visible; on a phone it opens in the same one-pane history.
Select text in the PDF to highlight it; click a highlight again to change its color.
Hold Shift while dragging a rectangle on Linux or Windows, or Command on macOS, then choose a color to clip a figure or equation as an image highlight. Dismissing the color chooser writes nothing.
Use the reader toolbar to choose a persistent Light, Warm, or Dark page theme, and open Outline to navigate a PDF's nested table of contents.
Every highlight becomes a block on a notes page named after the PDF, so you can write underneath it, link it, and reference it like any other bullet — and each note jumps straight back to its spot in the document.
It's how you turn a paper into linked, searchable notes without ever leaving Tine.
