In cases when we have loadOnDemand set to true and we want to populate the value of the DropDownTree initially we need a way to check if this value is part of the available options. One possible solution is adding a valueMapper function similar to the one use in virtualization scenarios.

Set an indicator same way that grid already does but now in sheet cells when a record is 'dirty'.

Can we have a theme or feature of all input controls that can support floating labels like in google material design? 

The current material design theme demos do not show example of floating labels.

Currently you can clone the Pager to make it appear both on Top/Bottom. This should be configurable so that you can have in on top of the grid or the bottom of grid or both

It would be nice to be able to configure the grid in a way that when I collapse a group, the lines it was occupying are then filled up by the results from the following pages.

Kendo Grid currently only minimizes the results of the current page. It ignores the pageSize config we have set, not bringing more items to occupy the number of lines we have configured.

Here are some screenshots I took from the DevExpress grid. There you can see that the column year is grouped and initially the years 90 and 91 are expanded. When I collapse the year 90, the results from the year 91 fill up the space the other group was not using anymore.

The NumericTextBox should behave like standard input fields and automatically select all the text when tabbing into the control. This should work for NumericTextBox controls whether using inside or outside of a Kendo grid.

It would be great to have such controls as webparts/widgets to place in a dashboard where we could move them around the screen to reorder how data is presented with option to save/retrieve the layout from a persistent source.

In the dashboard the functionality would be to define a layout where we could add/remove, change position the widgets (like in dropthings or pageflakes). The widgets would contain controls like Kendo Grid or DataViz controls to display information.

That would be a killer feature.
