Save the current page or PDF to a side panel. Each item is kept as a complete snapshot, so it stays available offline.
You are working through a local documentation set and hit the page you will need tomorrow, on the train, with no connection. Bookmarking it helps nobody if the bookmark points at a file you will not have to hand.
Save the current page or PDF to the side panel. Each item is kept as a complete snapshot, the full page or a copy of the PDF, rather than a reference. It stays readable offline even if the original moves.
Filter the list by read or unread, mark what you have dealt with, remove what you are finished with. The list stays a work queue rather than a graveyard of links.
A bookmark to a local file is fragile: move the folder, rename the page, leave without the drive, and it leads nowhere. The snapshot carries the content itself, which is precisely what you want from an offline reading list.
A PDF saves like a page. A documentation set mixing HTML and PDF is therefore prepared in a single list, with no need to handle the two formats separately.
