extension support, custom search engines, saving page as pdf, article reading mode features should be added. Som people use search engines like ecosia and, I like using article reading mode because it is simple and does not tire my eyes. I rarely use pdf option but can be added.
Reader mode: Settings > Accessibility > Simplified view for webpages 🤷
And they’ll add Ecosia for the default options, FYI. In an upcoming release. Maybe 2 versions away.
Last time I heard, they are working/exploring the possibility to add extension support for Android.
And my +1 for pdf.
