- Filter by date range - SyncUpdate tasks run fully asynchronous in background - Move tableView manipulations into FilterPipelineDelegate - Move SyncUpdate notification into SyncUpdateDelegate - Fix: sync cache before persisting a recording - Restructuring GroupedDomainDataSource - Performance: db logs queries use rowids instead of timestamps - Add 'now' button to DatePickerAlert
