Stop your feed showing you everything

There is too much in it, or you only care about a few people right now.

Steps

Tap Feed in the bar at the bottom.
It opens on the Friends tab; Groups and News are beside it.
Open Friends Feed Control at the top.
It is a panel with a ⌄ — the filters live inside it rather than cluttering the list.
Tap a person's name to see only them, or All to go back.
Every friend who has posted gets a chip.
Choose how saved items are treated: Include Saved, No Saved, or Only Saved.
Only Saved turns the feed into the things you kept.
Set Relevancy if the list is still too long.
It is a percentage — raising it keeps only what scores above it.
Tap Refresh when you want to pull anything new.
Next to it, Settings holds the rest of the feed's options and + Invite brings someone in.

You will know it worked when

The list redraws to just what you asked for. Each remaining entry shows who it was from, what kind of thing it was — Joined Group, for instance — and how long ago, with vote arrows and Reply on the row.
