Currently, there is no ItemTemplate for the SegmentedControl, therefore we need to use an IEnumerable<string>. Please add support for ItemTemplate, or DisplayMemeberBinding property, so that we can bind to an IEnumerable<T>.
Currently, we have exposed a limited set of properties which you can use for styling the items. We should consider adding additional ones like Text alignment, TextFontSize, etc. Setting a separate Control Template might be the best option.
Provide support for multiple rows of segments. Additionally, ad properties that help manage the wrapping behavior. Some example property names for such a feature: AllowMultipleSegmentRows="True" MaximumSegmentsPerRow="3"
If the SelectedIndex value set is outside the items bounds, automatically select the first or last item instead of throwing a NullReferenceException. Ex. Similar to the behavior of the Xamarin.Forms Picker control.
