Kendo UI mobile widgets are really falling behind and now need an urgent refresh. Most mobile widgets have not been updated in 3 to 4 years (https://github.com/telerik/kendo-ui-core/tree/master/src).

The most urgent is for styles to be updated to match LESS and SASS styles. Currently, styles are a mess and making a mobile app including the grid and other recent responsive widgets with consistent styles takes a lot more time than it should:

- NOVA has many specificities not available in other themes

- OS skins have no match to style the grid and other web responsive widgets

- Material UI is not consistent and up-to-date

It would be really nice to have an easy way to dynamically create Kendo Windows in AngularJS. And also with separate controller and template.

Here i´m trying to do this but it would be really good to have a similar way integrated into Kendo. There is also a demo on the repo.

Integration of the pivot control with the spreadsheet

A recent update added the Checkbox widget that uses a novel set of CSS and HTML elements to stylize the checkbox in the browser.  This style is not automatically applied to the TreeView widget's checkboxes.

It would be very nice to have the TreeView checkboxes stylized to maintain a consistent look and feel across widgets:

Kendo UI supports PDF export. It would be great if you could add glyph mirroring support to it as well (https://github.com/mozilla/pdf.js/blob/master/src/core/bidi.js). PDF export of RTL languages such as Arabic and Persian need this trick to work properly.

Allow creation of custom labels that can be placed any where on the chart surface using x, y coordinates.

We have the needs to display a toolbar vertically. We tried your toolbar control but the feature was not there. However, we looked at the code and did minor changes to allow it. Is there any way we can submit the code so you would look at it and maybe add it to the main stream of Kendo UI javascript toolbar?

Support for injecting some custom header information in the export PDF and Excel? 

e.g. You are exporting some grid to excel or pdf and you want do display the search parameters in the header of the document.

Extend "filterable" to match the datasource's "filter" (singular, not "filters") configuration option.

I ran into this problem wherein I receive a 'Maximum stack size exceeded error' when I try to bind a collection with circular references  to kendo ui grids and data viz charts.  My Angular SPA is using breeze to fetch server-side entity models. As these are entity models, they do have circular references. I am also using the angular-kendo library for the directives.

Current fixes include manual removal of such entities from the collection. It would be great if the controls can handle such collections.

I would like to define a template or a message or something such that when there's no events the scheduler doesn't just look like a smushed collection of buttons, or having to set a min-height on the event zone or some other hack.

We would like an event that we can listen to for when the drawer has completely finished opening.

Extend Dataviz Diagram to implement a BPMN Editor using

It would be nice if it will be possible to bind multiple viewmodel to a single DOM container. Like xaml binding in witch you can specify a "Binding Source" adding a simple way to specify different viewmodel can help in many real situation. The solution can be accomplished very easily. If you introduce an override of kendo.bind in witch u can specify a key string for identify a viewmodel then with a data attribute or a custom binding you can filter when activate or not the bindings. 

Please see 'Subject' line the <div> resizing didn't work as advertised and the splitter itself resizes to '0px'

There should be the ability to show resources (this is multiple resources) without grouping. All resources will show in a line. This would have worked in our case where we have employees and sub-contractors as two different set of resources but cannot be grouped. We needed to show both the sets on the scheduler at the same time and also assign events across to both sets (so an event can belong to an employee and sub-contractor). The two sets cannot be combined into one resources collection as the resources can have the same Ids

Useful for automatically splitting the major dimension of a screen/view, for example. Especially handy for supporting tablet orientation change.

Or, add an orientation() or setConfig() method, to support horizontal/vertical toggle via script.

At the moment the Scheduler allows multiple appointment selection with Ctrl key held down. I would like to be able to choose between Single or Multiple selection mode, just like a Combobox. I believe there are real and valid use cases to restrict users to 1 selection at a time.

I have a list view of unassigned users, I can drag and drop from listview into a treeview to assign them to a group node in the treeview. (This works) I need to drag multiple items to the same group node to add more than one person at a time.

multiple draggables to one dropTarget.
