@kallekn I wouldn't hold your breath for this, I don't think we're likely to implement this.
The default state for Mastodon (and virtually every list interface in UI design) is to have it scrolled to the top. And when the oldest, stalest post is at the top by default, there's not much value in seeing the same post at the top every single time you re-launch the app. It also just introduces a ton of weirdness around our infinite scrolling mechanisms, timeline positions, etc.
@samhenrigold For me, the default state is to have it scrolled to where I last was. Even if I relaunch the app. Works reasonably well in @pachli , I'm happy to report.
