When in NumericTextBox the cursor is in the input field, you can use arrow up and down to select increase/decrease the value (as if using the spin buttons).
Allow the use the mouse wheel to do that (only when NumericTextBox has focus)

We're providing a month by month summary of some information and would like to allow navigation and high level event occurrence using the Calendar. Currently the Calendar doesn't provide an event on visible date changes to figure out when we should change the summary information.

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). 

When manually entering dates, typing '0' in month or day section resets the text to the placeholder.

Normally when entering a number, the focus shifts to the next field when the required digits are entered. For example, entering '10' for the day section, moves focus to the month. 
When we need a date where day < 10 however, we need to tab or enter the date separator to switch to the next part.

Allowing 0 in the dates should improve the users speed for entering dates and create a more unform behaviour.

Currently situation:
Date: 10/12/2017 => user input: 10122017
Date: 01/01/2017 => user input: 1/1/2017

When allowing 0 the last date can be entered as 01012017

Allow using current switch in a trivalent state (i.e. : true,false,undefined)

Please add modality configuration on dialog service so we can have something similar to kendo ui windows 

Please add width configuration on dialog service

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

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.

Be able to turn off Keyboard Navigation for Kendo Component for Angular 4. (Not just for buttons)

Sometimes, our app may certain key down registered for other events but Kendo's component's keyboard navigation can't be turned off easily and will take over our app's keydown.

For now,  we have to write wrapper for every component that we don't want keyboard navigation like this:

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"

   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

When do you plan on releasing the Color Picker?

Any plans for a UI Query Builder that uses the Data Query component?

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.

Spreadsheet control as a separate component, or Grid control updated for AutoCOmplete and drag fill capabilities

The new calendar and date picker input components are great, but they are missing a significant functionality which has been available for a long time with the jquery calendar date picker -

The navigation is very basic and does not allow high level of years navigation - it requires monthly scrolling. This is very limiting for users who need to select a date between wide ranges. 

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