Similar to the DialogService, adding a toaster module / service to show short message on the screen. As hint, look at the ng2-toastr node module.

Similar to the context menu in the jQuery suite - http://demos.telerik.com/kendo-ui/menu/context-menu

Make charts scrollable like how Google Charts implementing it: 
https://developers.google.com/chart/interactive/docs/gallery/controls#chartrangefilter

It should be possible to apply missing semantic information to the rendered code of a web application to support handicapped users to get the most possible benefit of the Kendo UI framework. 

Not being able to have multiple series with their own y-axes on the same chart is a dealbreaker right now.

Equivalent functionality in jquery: http://demos.telerik.com/kendo-ui/bar-charts/multiple-axes

I suggest to add a angular service similar to the dialog https://www.telerik.com/kendo-angular-ui-develop/components/dialogs/dialog/service/ for the window
Thanks

Option to position the title or labels outside the chart. When you have negative values in the Y axis, the title is positioned inside the chart near the 0 value axis and not at the bottom of the chart.

In current version of Kendo UI for Angular 2, there is no control for Menu or Navigation bar. It would be nice to have a separate component for routing

Should have features on previous web technologies. What's the point of going new, if features are missing? 

There is no solid date range picker out there. It would be perfect for the great arsenal of date / time pickers you already have.

To - From date in one component.

Would be very helpful

There is no such component as tooltip.

Something similar to old tooltip:

Our team would love to be able to use a Material theme, similar to the theme found in Kendo JQuery.

Modeled after the jQuery widget counterpart:

   I see Kendo Window widget is not available for Angular 2 , so we are ending up using jquery with Angular 2.  We couldn't find this component it in road map also. Please let me know is there a plan to release kendo window angular 2  in near future?
Thanks

similar to the Kendo UI Window for the jquery version
(http://demos.telerik.com/kendo-ui/window/index)

I would like to see Gauge components will be supported soon,

Allow the placeholder text for the date picker to be customized. For example, some may prefer "MM/DD/YYY" to be displayed instead of "month/day/year"

Provide support for the components.

Interestingly I can't select Charting which is the component I need support for.

Please improve!

Allow the selection of a month and/or year in the datepicker.

The datepicker in kendo ui for JQuery allows us to select a month (without day segment).
