Click New and then choose template “New paper”.
Fill in URL and optionally, the paper’s abstract or your own summary.
A long abstract will create imbalance interface, which makes it harder to see and manage the list. Therefore, this template will automatically take the last sentence of your abstract (if not empty) to display.
Mark a paper as Finished Reading will move it out of the way into a dedicated view.
You can still see all papers at once in “All” view.
