It would be really nices to have the possibility to customize the kendogrid buttons icons (for example using Font Awesome) 

For example the Save changes and Edit changes button's customization is not supported

Export the entire Kendo Window or Modal WIndow contents to PDF/PNG

As Kendo UI already supports AMD Require, it should also be support CommonJS and Browserify.

Would be nice to have a validator that validates not HTML elements, but  model properties (after all when using MVVM HTML is bound to properties). Consider the following scenarios: A property is not directly bound to an HTML input. For example, I have a collection propery and my model is valid only if it contains at least N elements. Or if collection elements have date or time fields, overlaps are not allowed, and so on.

As there isnt a pure spreadsheet control, adding this function will allow users to still make changes in excel but visualize it in the app.

I hardly found 10-12 themes and none of it other than blue-opal looks good on UI. Please add some good themes.

The "Image Gallery" sample contains more than a nude picture; yes it is an art, but I think it is not suitable for many people including me, seeking for technical help or demos.
Please keep this perfect technical site clear and focused.

Yes, the image list is dynamic and the data source may be outside Telerik servers and control.

Thank you for your great products, tools and samples.

Using the drawing API, we can draw on the chart itself for flexible annotations.

My grid with server side filtering returns 3 rows. But the returned rows are hidden by client side filtering. It shows no rows. For example: My filtering on server side returns 15 rows in two pages (pagesize: 10). But the client side filtering hides all rows but the single row satisfying the condition which is in the second page. So all records in the first page is hidden. In my opinion, all 15 items should be displayed. or the record satisfying the condition should be shown in the first page itself.

Kendo UI has accessibility built into it.  I do not know why you do not have it for Kendo UI Mobile.  Accessibility is still needed on mobile apps.  I know Android does not handle it will, but iPhones do using VoiceOver.

[a] On paste
    [1] If pasted text contain email/url then convert it into link.

[b] On typing using keyboard in editor 
    [1] If Email is typed in editor then convert it into email link (href should contain mailto: attribute).
          for example if you type abc@pqr.com then its link should be like (<a href="mailto:abc@pqr.com">abc@pqr.com</a>).
    [2] If URL is typed in editor then convert it into URL link.

Kendo grid column custom command should either have option to pass template or have dataItem as default parameter along with jquery event.

Currently cannot get the dataItem

Chart legends should be draggable, so if it overwrites any chart lines, user can drag them away easily.

It would be nice to have tooltips showing when the user hovers a shape on a map, basically the same funcionality that can be obtained for markers.

Stacked bar chart issue, undefined is shown in the series where a category data is not available among the series.

PDF Export required a new method which will open on new tab instead of downloading it.

eg:  kendo.drawing.pdf.open(group,"Invoice.pdf") 

Can you provide grails with kendo ui configuration steps
