I found this question, which has two similar answers, both about Foliate. https://askubuntu.com/a/1323672/124466 and https://askubuntu.com/a/1323699/124466
Is it a good idea to keep the better answer, and remove the link only answer?
This question has so many answers that it would be hard to know about other applications, if there are multiple answers about a single application.
This issue of duplicate answers are present in some other highly voted questions as well.
