I browse HN from https://hckrnews.com/

It's chronological.
Never used any of the other filters. Maybe that’s why.
All does everything I want.

Every entry on hckrnews has hit the homepage, so 'all' is exactly that. The current homepage filter is simply a filter to show what is presently on the homepage of news.ycombinator.com.
But this is not the first time someone has been confused about the homepage filter, so I could probably explain that better somehow.
