Speedreader should not omit relevant information about an article. The date an article was written is fundamentally essential information for evaluating the relevance of the content. And it should go without saying that not crediting the author is inexcusably disrespectful. There is really no reason not to include any reference information provided in the heading of an article.
Quick comment: depending on how a web page is coded, Speedreader may not be able to deliver what you’re requesting. As I understand it, Speedreader merely ‘distills’ the text content from a web page. If portions of a web page (e.g., the author’s name and an article’s date) are other-than-text (perhaps for aesthetic / editorial reasons), Speedreader may suppress rather than display these elements. It’s content-agnostic. Yes, I agree with you about the importance of author and date, but Speedreader can’t ‘intelligently’ select for that in a web page’s other-than-text content.
FWIW, I find the elements of a page that Brave doesn’t display - as an aspect of how Brave does its job - accomplishes most of what I would want from a ‘Speedreader’.
Can you offer any examples of Speedreader suppressing a by-line and date when these elements are part of a web page’s text content?
