Lecture video embeds
Layer video (direct upload or YouTube/Vimeo), GIFs, and widget embeds onto the material. Autoplay, loop, and mute are each adjustable, and playback happens in the web viewer. Switch on the QR option and downloaded PDFs carry a QR code in each spot, so even printed handouts lead to the videos.
Page-jump buttons
Lay click areas over the document that jump to a chosen page. Put per-unit jump buttons on the table of contents and even long materials navigate instantly. Page jumps work in the web viewer and in downloaded PDFs alike.
Completion & per-unit stay
Average completion, per-page stay time, and return-visit share together reveal which unit loses learners and which pages get re-read.
Revise behind the same link
Typo fixes or a curriculum overhaul — just upload the new PDF. Links already distributed show the latest material, and you can roll back to a previous version instantly.
Learners only
Limit opening with an email allow list or a password, and let an expiration close the link when the course ends. Issuing separate links per cohort keeps things tidy.
Course bundles
Bundle each lecture's material links into one data room and hand it over like a course page. Every link keeps its own password and expiration settings.
