Buttons adjust by day or minuteIncrement. Minute values are now always rounded to multiples of minuteIncrement, unless freeMinuteEntries=true (or minuteIncrement=1)
ToDo/Questions Nathan:
- Tracker index gives a client-side TypeError
- <et2-select-account readonly="true" is not registered, but <et2-select type="select-account" readonly="true" works
- <et2-date-time was registered as <et2-datetime, was that a typo of a conscious choice to rename the widget and not just prefix with et2-
- not yet enabled are r/w et2-date(-time)
- still missing are r/o et2-date-(since|duration)
