Needs : ItemAppeared, ITemDisappeared, Refresh, IsRefreshing, IsPullToRefresh

Waiting impatiently for ItemsUpdatingScrollMode

We really need ItemAppearing.

Please add GroupItemsBinding to embed child collections instead of forcing groups to inherit from collection.
See xamarin/Xamarin.Forms#3172 (comment)

Have needed this for years on many occasions.

Support multiple grouping levels (tree)? See xamarin/Xamarin.Forms#3172 (comment)

Forms.SetFlags seams not to be implemented for WPF, so it not possible to test on this platform ...

Waiting for SelectedItem support in UWP.

Waiting for RemainingItemsThreshold/Infinite scrolling.

Dang. Need RemainingItemsThresholdReached!

Please. This is a terrible workaround http://www.codenutz.com/lac09-xamarin-forms-infinite-scrolling-listview/

@IgorKravchenko10 @donatellijl @Bronson15 There is an active PR for infinite scroll. xamarin/Xamarin.Forms#5754

UWP SelectedItems and SeletedItem PR xamarin/Xamarin.Forms#6629

Please add drag and drop functionality to this new ListView so we can arrange items in it by simply dragging and dropping

I see that Grouping is marked as complete here but in the docs it's stated as iOS only. What version is it complete in and can the docs be updated?

Needed ItemAppeared, ITemDisappeared.

Need Dynamic Item Sizing on UWP. I've opened an issue for it here: xamarin/Xamarin.Forms#9056

When will WPF support be added?

RemainingItemsThreshold for UWP -> Any PR I can subscribe to? It's required for a Project im working on to have consistent behavior on iOS/Android & UWP

Dynamic item sizing now works

Is there a plan to add MacOS support?

Is this currently updated for Xamarin Forms v.5?
