I am loading content into the window asynchronously and would like to see an event that I can subscribe to that would fire when this content has finished loading.

We should not lose functionality that the jquery dialog already supports.   Keydown is an important aspect in many web apps and right now a user can click the escape button if entering in a bunch of data and it closes out the window.

Currently, a modal window allows for tabbing out of the window to controls on the page below.

On a web app I run into the problem where the dialog is dependent on a grid row to be present, but due to tabbing out of the not so modal window I can delete the applicable grid row removing the context on which the modal window is based.

This is a bug.

Currently kendoWindow class publishes a "minimize" event but not the corresponding "restore" event, as far as I can tell.  We need to catch the "restore" for our UI case, as follows:  The default Minimize action leaves the window width unchanged, and collapses the height to 32 pixels.  But we'd like to also shrink the minimized width, in order to further save space.  It's easy to do that, via the minimize event, but then getting the original width back upon Restore is a problem - I can't find a straightforward way to do that, because the presence of the Restore button ("k-i-restore" class) is elusive - it isn't present at startup, nor is it found at the end of our custom "onMinimize" method.  In the absence of the "restore" event, if anyone can suggest a straightforward way to accomplish the above, we would be grateful.

I have this problem where I use the window but I turn off your titles and use my own custom made because of the specifc layout I have. But by doing so I lose the option of making the window draggable since it can only by dragged by its title. Give us a simple config option to set any elements inside the window as the draggable points. That way I can set my own header and make the window draggable by holding it.

Windows should be able to be contained or restricted to a specific area.  This can either be using parameters or by containing it to a parent object/DIV.  

Reasons:

Windows can be dragged anywhere on the browser document and when maximized they take up the entire document.  This is a problem if you have an area of the document that you always want to have visible.  In my example, I have a toolbar at the top of the screen 25px high and I would like the windows to never move into that area so that it is always accessible.

add sure/cancel button on the bottom(default) of Kendo window component

Please consider adding an option to Kendo Window to make it always centered/fixed. This will be essential for Modal windows/dialogs to always stay in the middle of the screen if there are scrollbars on the page. I would go as far as suggest making this the default behavior for windows with modal: true.
