Reading list
Reading list in the sidebar holds what you saved to read later: pages from the browser extension's Read later in Notii, pages shared from your phone (Add to my reading list is on when you share just a link), and any note you add from its ⋯ menu (Add to reading list).
Each one shows its site, how long it takes to read and how far in you are. Notii remembers where you stopped: open it again and choose Pick up where you left off.
At the end of the note, Mark as read moves it to Read (the switch at the top of the list). The ⋯ menu marks it read or unread, or takes it off the list.
Coming from Pocket? Reading list → ⋯ → Import from Pocket… brings in its export (the .zip, .csv or .html): pages you hadn't read go on the list, archived ones come in marked read, with their tags.
