Feature Request: Option for not marking as read until scrolled to the bottom

[dgriffinjones]

I would like an option in the Settings panel to not mark an article as read until the entire article is read, or, only marking it as read when scrolled to the bottom.

I often begin reading an article on one device, get distracted, switch contexts or devices, and forget to come back to it. It’s marked as read and disappears from my unread list on other devices before I’ve finished it. I would find a setting to change this behavior, on both Mac and iOS, very useful.
