Fold a group away

Grouped tables and lists fold now: a chevron on any group heading folds its rows away and leaves the heading and its count. What you fold describes what you’re looking at, rather than what the view is, so it doesn’t save with the view. Changing display starts every section open again.
Smaller changes
- The sidebar takes three settings: always open, always folded, or automatic, and Cmd B steps through them.
- The inbox and Notify me are on for every organization now, rather than switched on one at a time.
