⛶Zoom the day until every quarter hour shows

A busy Thursday and a quiet Tuesday do not want the same hour height.

⊖ and ⊕ at the foot of the day make each hour shorter or taller, and the app remembers where you left it. On a phone you can pinch instead.

⛶ takes the diary out of the page: no top bar, no tab strip, just the day. It is the view for the morning look, and for handing the phone to somebody to point at an hour.
