Fixed "Controller 'list', required by directive 'listItem', can't be found!", https://docs.angularjs.org/error/$compile/ctreq.
List items are now hidden by default in focus tasks, because they use a custom filter which may not yet be registered into list directive. 'list' directive is no longer optionally required by 'listItem'.
Fixed a bug in focus tasks where yesterday heading was not shown as a past date. Optimized day slides data initialization by referencing to slide's reference date instead of creating Date object.
Updated AngularJS from version 1.3.0 to version 1.3.2.
