Build a Kendo Pie chart with long label names in the legend.
Hover the chart close to the legend - if the area around the chart is too crowded with legend labels the tooltips (supposed to be displayed in that area) are actually placed very far from the chart, leaving the chart container.
Maybe it would be beneficial to replace the absolutely positioned tooltip <div> with an svg representation.

Hi Teleric,

could you incorporate a full calendar (day, week, and month views) like this:

We want the Grid fix the remote virtual scrolling with groups. 
In this case the Grid stay launching requests indefinitely.

Please consider adding animation to the slider control in a similar way to the linear gauge or the ajax slider control.  this would add an extra dimension to the controls capability

Logarithmic scale for charts

I've been using nRoute framework on silverlight, and some MVVM features that it provides, really is a miss on kendoo ui. 

for example some of the "killer features":
1. On a view, you can apply url like template attribute ("Content/Views/functionality/Loadstuff/{AccountId}") and the internal routing will find that and initiate, when it is called via global static navigate method.
2. The binding of View and ViewModel is done very well. On the view model, you apply attribute that this viewmodel is working with this view.
3. Containers. You can call navigate url, and get the rendered viewmodel. This helps application composition as you can have a some layout templates, and apply custom attribute on div, like "container-url" to some internal url, and it will fetch the rendered view and put it there.
4. Communication framework. Literally a Pub/Sub.
5. Modules/Dependency tracking. For example, i have SPA application, that loads some basic controls for js, and when user clicks reporting, it will check that reporting is dependent on Dataviz, loads dataviz, and loads viewmodel.
6. Behaviors, very common things, like, ValueNotNull, ValueNull, BooleanValue for someexpression. This allow you to create more dynamic ui, without adding new code in your viewmodel

In the NumericTextBox typing the character "-" is not allowed meaning that the user can not directly type a negative number.  The only way for a negative number to be specified is by clicking the down arrow to progress below 0 to get the dash to show up.

Some strict JS parsers (eg. YUI minifier) may throw exceptions when you use reserved words as variable names. Please, do not do this.

Within the Grid you can currently either have single-row editing, or batch editing. However, batch editing does not necessarily show the end-user that the Grid is actually editable. In order to make the Grid more intuitive it would be great to have all cells display their edit template constantly to ensure that the client knows they can edit the component.

Additionally, sometimes a user will want to edit more than one row at a time, but not have the entire Grid in edit-mode. Being able to open several items to be edited at once would help with this user interaction.

This is why having multi-row edit, the ability to have multiple rows in edit-mode at once, would be a nice feature to have in a Grid. It would also theoretically open up the ability to have all rows in edit-mode at once.

With the release of TypeScript by Microsoft it would be great if there would be a definition file for the different Kendo Libraries.

I actually played around with it myself, implementing some basic functionality from the core and the Calendar widget. This is by no means complete or error-free, but it gives an idea of the possibilities. I was able to get all the nice features TypeScript has to offer (e.g. type checking, auto completion).

As nodejs + express + jade is here, i think you should have more examples with jade and nodejs...

I'd like to use Kendo, but the available themes are too restrictive, much less vibrant that the MVC themes.  And the Themebuilder is not adequate to extend or alter them.  Can you add richer themes to Kendo?

A ListBox widget with the following core features: skinnable, drag and drop to transfer items, ajax binding, support for templates.

I have seen a few different samples on how to implement a dynamic skin chooser for Kendo UI Web, but I think this would be a great UI control to be added to the suite itself.  None of the code samples I have found are simply drop in and use, but require slight modifications.

Slider seems to only output numbers, I want to use it for date ranges, ala mint.com.

Validation framework is great, but too much of a black-box.  No way to understand what failed.  For example, try using a bootstrap styled form, and have kendo validate and add/remove bootstrap error/OK styles from parent elements using onblur.

When I hit Update wizard, there were pending changed in TFS so the Wizard made me confirm the update failed 849 times

There are some bug on parseExact function where check literal return value is not checked producing as consequence that invalid dates are accepted.
You can see this in http://jsfiddle.net/OnaBai/LnaTq/1/
Where I show that a date as String that equals to 2012-09-26 and parsed with format HH:mm is recognized as Jan 01 1900 20:12:00
because the 2012 gets converted into 20 hours and 12 minutes.
As I mentioned above the bug is due to the fact that checkLiteral return value is not tested in parseExact function allowing the execution to continue skipping the ':' of the format string.
If you want me to send you fixed solution I have already implemented it. By the way, watch out that all but one checkLiteral should be checked for false.
