It would be very helpful it there is an option to hide spin controls on numeric controls. Spin control are not really useful in all cases. Also setting readonly property for the control has no effect on the spin control you can still update the value by clicking the spinner. Currently in the forum a workaround was suggested using css (http://jsfiddle.net/krustev/uZUjK/). Implement this as a property for the numeric control

When displaying a large list (hundreds of items) in a list-view it takes a long time with many flicks to get to the bottom. I've been testing on a Galaxy Nexus, and in my gmail I can get to the bottom of my list of  emails (hundreds) in just a couple of flicks.

It seems the kinetic scrolling in kendo ui mobile doesn't scale well with longer lists, it scrolls the same number of items no matter the size of the list. Whereas the native behaviour seems to keep scrolling for longer and faster, scaling with the size of the list.

When the kendo grid is in batch editing I would like for the keyboard navigation to respond like a spreadsheet.

Here is an example: http://plnkr.co/edit/hy6Evh?p=preview

In the example the keyboard navigation more closely follows an Excel spreadsheet.

Here are the specific interactions that I noticed that are different.
- when focus is in cell it is automatically put in edit mode. No need to switch to edit mode.
- enter, shift-enter, moves down and up.

I have observed that my users are more familiar with Excel keyboard behavior than the current Kendo grid behavior.

Our team immediately noticed the different behavior of the Kendo DropDownList. Exactly as outlined in this forum post: 

http://www.kendoui.com/forums/ui/dropdownlist/dropdown-list-and-using-alpha-key-for-next-item.aspx

Hitting the same alpha-key multiple times should cycle through the entries that begin with that letter.

I use a timebar + sparklines in all our dashboards.

would be great to see an html5 version of the executive dashboard

If I have a list view, and I want users to be able to drag and drop to re-order things. A config option of reorderable that would use your drag and drop kit would do the trick.

Adding a "select" when user choose one of the hint in AutoComplete to help field-linking.  More detail and implementation about the idea in here: http://www.kendoui.com/forums/ui/autocomplete/suggestion-about-select-event.aspx

It would be great if there are customization of categoryAxis label when ploting has both +ve and -ve values. 
The label need to be settled down at bottom (base line) automatically when there are negative values and same for +ve values.

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.

Add extensions for templating engines such as JADE, HAML, or JQuery Templates, so Kendo UI can be built from VIEW files in MVC frameworks such as Express or Kanso on NodeJS.

How about a easy way to build reports like invoices, labels, etc?

This bug is visible in your demo at http://demos.kendoui.com/web/grid/editing.html.

When using a scrollable, editable grid in IE (9 or below):
•	Scroll down so that the first row of the grid is no longer visible.
•	Click on any row.
•	The grid jumps back up to the original "unscrolled" position. (In your demo, on my screen, this means that only the first 10 rows are visible.)
The result is that I am unable to edit any row outside the first 10, unless I use the keyboard to navigate.
This does not occur in Firefox, Chrome, Opera, or Safari - only in IE.

Dropdown with Multiselect ability and no linebreaks when too many Items are selected just a simple ellipsis at the end.

like this:

We find with lots of UI vendors put up cool demos, but rarely a more realistic view. We like to see the controls in a LOB style layout with:
1. A Purchase order where you enter PO#, Date, Customer (Autocomplete), Customer Name (as result of autocomplete select), ShipToCountry.
2. Order lines (grid or other) with ProductID (autocomplete which then populates description and price), Quantity (which in turn calculates line price).
3. As a result of ajax submit, the server side validation returns error saying order value exceeds customer limit AND ShipCountry not valid for this customer. So the form displays message "Exceeds customer limit" and ShipToCountry input is highlighted with error message "Not valid for this customer".

And make it look good!

In case there are a couple of opened modal windows(win1, win2, win3, win4) after destroying one that was closed(win5) – two next in chain(win3 and win4) becomes enabled, instead of only the last one(win4).

I’ve analyzed the code of method kendoWindow.destroy and found following lines 

if (shouldHideOverlay) {
    that._overlay(false).remove();
} else if (modalWindows.length > 0) {
    windowObject(modalWindows.eq(modalWindows.length - 2), that.options.name)._overlay(true);                 
}

It seems that line 
modalWindows.length - 2 
should be changed to
modalWindows.length - 1
as modalWindows holds currenlty opened windows, and overlay should be turned on for the last one.

Could you guys add normal user controls like a dropdown list on the mobile framework. On the android the <select> element does not work. It's grayed out?

Provide context menu support for treeview. At least provide mouse click handlers for treeview.
Also how to add items with id from datasource in treeview. You have API to select via item id, but nothing that adds id via datasource.

Similar to jquery mobile, it would be useful to handle below events
- touch (with fingers, directions)
- tap
- tap hold
- swipe (left / right)
