/all doesn't have autoscroll, only /all/new does.
It's been designed that way because the goal of /new is to scroll through new submissions.
The submit buttons are only showing on top in subs to simplify their accessibility.
I'm not sure if adding them on top in /all/new will improve users' experience as they will still have to scroll back up, tap on one of them (text or link post), and manually type the name of the sub they want to submit to. What do you think?
