since you need a button to jump to next unread (something) this means you’re reading sequentially anyway - why not just open all articles and read that instead, which would solve your problem without adding UI bloat
a much better idea however would be learning to organize your data better with stuff like scoring and filters.
yeah i’ve just removed almost this exact thing from tt-rss proper, how likely do you think would be introducing it on android now, lol
that aside, i imagine scrolling a bit too much by mistake and oops the app takes you somewhere without notice, how annoying - but why not make this an option, right? wrong. terrible idea.
