Oh maybe it's already working like that, or there's some bug?
When I go to https://stacker.news/, then the label says "top", but the items are not sorted by votes.
It's just labeling the button, not the current sort. The sort of the homepage is 'hot.' I kind of intended it as a customizable button which goes to either 'recent' or 'top' depending on what you viewed last. It's not a normal UX pattern but it's what I wanted.
I see. Ok, that's reasonable and probably learnable. :)
