Neither I nor anyone at my company can get it to work. We get a link in a email and the page fails to load at all. That means that I can't get a demo version of the project, I can't post in your forums, and I can't contact technical support. And you don't have a phone number on your site, so I can't contact you that way. If the only way of getting to you is via registration then you really need to make it work properly.

Kendo UI for mobile, should provide a default look for NON mobile device. 

The vertical scrollbar is visible in Firefox but not Chrome, but only when using virtual scrolling. For Chrome users, it's impossible to see that there is more data available like this... See e.g. here: http://demos.kendoui.com/web/grid/virtualization-local-data.html

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

The keyboard navigation does not work on grid. Please see the sample "Editing Custom Editor". In the previous version you can edit one cell, hit enter or tab key and then move to the next cell o using the arrow keys, move the next row. Thanks for creating this amazing tool.

Grid on grouping show count of the grouped items in the group header. Its a pretty known functionality.

Support the same grid footer templating as in asp.net ajax with the same default options for recordcount, pagechange slider etc. 

To make it easier to add Kendo UI to a project, create a Ruby Gem package.

View/edit source option to edit raw html inside the editor.

Probably a looong shot but I vote for prefixing all Kendo functions with simply "k" instead of "kendo". All CSS class names (and Telerik MVC Extensions) simply use "k" (or "t") and that would be great if the rest of the framework followed this approach...

Having the ability to create "WYSIWYG Text and HTML Editor" would be excited.

For example a guestbook, I want to show the first 10 entries, when the user hits the "show more" button, the next 10 will be loaded and added bellow the first 10. Again, you can push "show more", loading the next 10, append them to the bottom of the list... till no more entries will be received by the server.
