Kendo UI has accessibility built into it.  I do not know why you do not have it for Kendo UI Mobile.  Accessibility is still needed on mobile apps.  I know Android does not handle it will, but iPhones do using VoiceOver.

I confess that I got surprised after checking Component One "Studio for ASP.NET Wijmo"! They already have super fast controls based on jQuery UI with support for ThemeRoller, and supporting client and server side operations. Why did you decide to go for the client side approach?! Also, the controls work really fast and have nice widgets like differente types of galleries. I hope Telerik decides to go this way with Kendo UI.

When integrating the Kendo UI Editor with other components, it would be nice if there was more visibility and control on the state and actions of the Kendo Editor.

For instance, bind 2 new callbacks/events: 
- onClose: function(event) {}
- onOpen: function(event) {}

Methods to control the Editor externally:
- editor.close()
- editor.open()

Methods to inquire on the Editor's state:
- editor.isOpen()

It would be stupid awesome to have a custom theme allow for selection the new project wizard!  That's consistency promotion!

I need to display multiple charts on one page. These charts are all based on the same timeserie.
To help with data analysis, I need to align every chart and the easiest way to achive that would be to be able to specify a width for the plot area.

Would you consider adding this feature ?

I know there are a number of requests for this, and I'm in agreement with all of them. I wanted to post a couple of specific examples in order to make it clear what would save me (a developer using Kendo for production code) time in implementing widgets within our application.

1. Provide information about all aspects of any given topic. For example, I recently tried to understand how sorting works for Grid. (see  http://www.telerik.com/forums/where-is-the-documentation-on-performing-case-insensitive-sorting-for-grid). It seems like it would take a pretty minimal effort to include information in the docs for grid column-header sorting (http://docs.telerik.com/kendo-ui/api/javascript/ui/grid#configuration-sortable) that describe how to turn off case-insensitive sorting, as well as explain that the grid option does not sort data on initial load (for that you need to sort on the dataSource). It required a fair amount of searching, and a couple of days to come to this understanding, which could have completely been avoided by adding a paragraph or two to the docs examples I just mentioned. For any configuration option, or feature documentation, make it complete and describe it entirely.

2. Utilize hyper-linking more effectively within the docs. A while back, I wanted to understand how to fully utilize the numericTextBox widget, and the docs mentioned 'format' for numerics. Unfortunately, I don't know what 'format' means in the context of Kendo widgets. Eventually, I found this forum post: http://www.telerik.com/forums/where-is-documentation-on-format
As I pointed out in my comment in that post, there's simply no reason to require your users to search for what 'format' means, when with minimal effort on your part, a link can be added and I can simply click to that documentation and get the answer I need.

There's a ton of individual examples that fall into one of those two categories, and if those were fixed, about 60% of the documentation issues I encounter would be resolved. I appreciate the chance to express this, and thanks for your consideration.

Please support the ImageBrowser as a standalone control.

I would like to have a chart like circular progress chart that use in lots of infographic diagram like the one below.

http://stackoverflow.com/questions/11202920/circular-radial-progress-bar

I managed to make it work by doing some manipulation to the donut chart like the one below that look similar to it but I believe the Kendo team can come up a better one and more reusable.

Add the AJAX FileExplorer to the MVC Controls Toolset with additonal built-in features I would like to see:
1. Support for UNC paths so that the root folder may be located in a network share as opposed to a folder under the application folder.
2. Support for sub-pathing so that it can be dynamically programmed to support direct display of target folder without having to navigate to the target folder
3. Built-in Delete function to complement the built-in Upload function
4. Optionally select display of a checkbox column to allow for multiple selection for items to be Deleted or Downloaded
5. Built-in Progress Bar for Upload and Download functions
6. Optionally select automatic filtering of hidden files and directories from the display

Currently min and max on DateTimePicker does not restrict time ranges. It only restricts min datetime and max datetime. 
Not time range within each date.

We need possibilty to set min time and max time to select like time picker has.

We need the ability to modify the title of the new predefined dialog control.  This control is a great replacement for JavaScript alerts and confirms.  However, we should be able to modify the title by passing in an additional parameter when using the control.

Below is a workaround using CSS:

    <style>
        .k-confirm .k-window-titlebar::before,
        .k-alert .k-window-titlebar::before {
            content: 'My New Title';
            font-weight: bold;
        }
        .k-confirm .k-window-titlebar .k-dialog-title {
            visibility: collapse;
        }
        .k-dialog .k-window-titlebar .k-dialog-title {
            visibility: hidden;
        }
    </style>

As of now there is no right click and double click events on diagram shapes, It will be useful if an event is raised on these particular actions. because these are the obvious actions on shapes

Changing the min / max value of the progressbar isn't possible.  For now, we have to destroy the progressbar and recreate a new one using the new min / max values.

Please add Breadcrum functionality in kendo.

it's looks nice if we have an option to move chatbot image to either on first or last of message for multiple messages (currently the chatbot image located on the last message)

A lot of app developers like the idea of adding a chat function to their app. In UI for WP Telerik has this beautiful Conversation View. Make the available as a full-blown widget für Kendo UI (mobile). Think of SignalR as a possible backend technology. Chat bubbles should have the ability to show text/pictures/emoticons. Provide a ready2use class for asynchronous or backgroud-sync (up/download) e.g. for ASP.NET Web API.

Please provide support of row grouping as it is going to be a very useful feature and excel is rich data file so we always need to group various sections. An example of the feature is available in the attached file and the link below.

Example for grouping data in MS Excel
