It would be nice to have access to a selectionChange event in the autocomplete similar to the other dropdowns. This way when binding against arrays of complex objects, we could receive the whole object selected instead of the single value property out of it.

I was a little flabbergasted when I found out that the "AutoComplete" component only handles "Simple Data" - even though there is a parameter called "valueField" and a subtopic under "Data Binding" called "Complex Data". It is impossible to display i.e. the Name of a Person and have the ID of that person as the value of the "AutoComplete" component. Can you please enable this, it is imperative to working with an autocomplete textfield that value and text can be _different_ and that a value other than the selected text can be accessed.

 With a combobox a user will naturally try to open the combobox, not type in it.  This is not a good UI design.

It be great to have a working and visually pleasing autocomplete component. 

Is it possible for you to change the combobox into an autocomplete component? Give it a parameter [autocomplete] and hide the dropdown widget.

Requesting an enhancement of the "virtualization" functionality for controls like Autocomplete and MultiSelect.  Currently, it only works for local data.   Would like to improve this to work with remote data.  It should raise an event when you're nearing the bottom of a page to load the next page, which would be done via an XHR call.  We have uses of these controls that could possibly bring  back millions of rows, so the current virtualization is of limited value.

You see this kind of "endless scroll" functionality in many places today, like a Facebook feed.
