Hello! 
You have cool Scheduler with timeline view (https://demos.telerik.com/kendo-ui/scheduler/timeline) without one important for us function: endless scrolling with dynamicly loaded events. When user scrolls near end (or begin) of current loaded time, control should send asynchromus request to server for next event data filtered by new range. Old data (events) could be removed from control

There is need to have multi-level Donut chart as shown in the link https://stackoverflow.com/questions/38560456/multi-level-pie-donut-chart-in-kendo

The chart here https://demos.telerik.com/kendo-ui/donut-charts/index does shows multi-level of information but it is not the same as required to implement the one shown in Stackoverflow query. 

In case the series chart with multi-level of information is possible with HtmlChart, please share sample code with data binding to implement the same.

Currently it does not support group/ungroup excel feature using kendo.ooxml.Workbook. Please refer http://prntscr.com/iykrqy for more detail requirement.

I've noticed that the Kendo notification widget is not response and does not wrap content as the browser shrinks.

We'd like radial gauges to have pointers we may customize, and/or to have a variety of pointerType settings, e.g., a marker that follows the circumference next to the scale; a custom image or shape that may be imported in place of the standard needle, such as the outline of a boat for heading.

Currently a tornado chart is not available in the Kendo Charts library. 

Is there a way to create tornado charts with telerik html charts?

It would be very useful from a visual and functional perspective to be able to view scheduler items in a multi-year view, that seems to be currently unsupported.

TOOL BAR Button Positions should have 
3 option:  right and left, and one stretched or not in the middle. That would be nice!

It'll be good to have such event for adding custom behavior to some of the child components.

It would help the user experience of entering times if the time picker had a styling option that would display a clock style interface where users can select the hour and then minutes.  This is similar to how time pickers work on mobile apps.

I'd like to have the ability for icons to be displayed in Internet Explorer even when web font downloads are disabled.

It seems the best way to support this scenario is to use inline SVG in order to support changing the icon colors.

Thank you.

Currently the Kendo AutoComplete only gives you the selected value, even though it received from the server a more detailed dataset.  The autocomplete really should be expanded to exposing the selected text and value, as well as expose the original data item that was selected; that way, the developer can access a lot more data from the control within the context of the change event.

Currently Kendo only supports TrueType fonts for embedding in PDF files. OpenType support would be great since it's a more modern format overall, and there are many fonts that are only available as OpenType (for example Google's Noto fonts).

I think it could be useful to have a configuration option that enables/disables the TreeView's connection lines

The linear gauge becomes cutoff at certain heights. If it's less than 50 pixels more and more features are cutoff. I'd like the linear gauge to be able to be 10 pixels without a cutoff.

Hi Product team!

I would love to have similar heat map chart on Kendo, as swimlane guys have:

https://swimlane.github.io/ngx-charts/#/ngx-charts/heat-map
or
https://swimlane.github.io/ngx-charts/#/ngx-charts/calendar


Thank you! otherwise you are doing great job.
