Add controls to selecting dates/times that also support null or blank values. Currently the DatePicker control that is provided as part of Xamarin Forms doesn't allow for a null or blank date. Provide the ability to select date and time in single UI.
Add public-facing methods to re-call DataSourceProvider GetSourceFor methods. This would allow for refreshing the datasource. Alternatively, add support for ObservableCollection to be used for DataSources so that the pickers reflect any changes to the underlying data source.
Region.Op.REPLACE is deprecated and therefore the exception is thrown:

1. Run app and apply a filter: "Contains 0"
2. Notice #40 is in the correct location, between #30 and #50
3. Press the button on the bottom of the page to go BlankPage and then navigate back.
4. Observe #40 is now at the end of the rows even though the filter is clearly applied.
Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed. I can reproduce the problem with both Replace and Add+Remove operations.public override void OnNavigatedTo(INavigationParameters parameters)
Currently, all groups are expanded by default. We should expose methods to collapse/expand certain groups. Furthermore, CollapseAll, ExpandAll groups should be considered as well.
