Taken from the StackOverflow question 'Why does 'show' event on Kendo View fire twice?' https://stackoverflow.com/questions/56266538/why-does-show-event-on-kendo-view-fire-twice

If a Kendo View is rendered into a Layout (using layout.showIn()), the show event for the view fires twice. Interestingly, if the view is rendered directly into a DOM element (using view.render()) the event is only fired once, like it's supposed to.

The code is pretty well copied from the Kendo UI Dojo thingee. I wonder if can you run this :https://dojo.telerik.com/AkOwiMAZ/2

<div id="app"></div>
<script>
var foo = new kendo.View("<span>Foo</span>", { hide: function() { console.log("Foo is hidden now"); }, show: function() { console.log( "Foo is shown now"); }});

var layout = new kendo.Layout("<header>Header</header><section id='content'></section><footer></footer>");

// Creating the layout, and using the showIn method to render the view
// is where I'm having the issue (2 'show' events fire)
layout.render($("#app"));
layout.showIn("#content", foo);
//
// But this way works fine (rendering directly to a DOM element) (just // one 'show' event fires)
//foo.render('#app');
</script>

With Vue.js integration started but not complete, I'd like to see the plan for rolling out the integration until it has parity with the existing packages like jQuery & Angular.  I'd also like information about any public beta versions so that I can plan for controls as they appear.  I have a possible long term upcoming project that I'd like to consider using these controls in, but without visibility into the progress it will be hard to justify using this package.

The routing framework should allow the developer to choose either the legacy # base routing scheme or the new HTML5 routing and History API.

This would make the porting of applications from other frameworks (AngularJS, Backbone, etc) that already support HTML5 routing easier.

Kendo editor should have an option to change it's colour tool (ex:- "websafe", "basic" etc.)

Kendo editor should change it's size according to the text inside the text area if the relevant option is set to "true"

Missing a real world sample of spa with shell's page + layers with AngularJS like we have in mvc/jsp/php demos.
why spa (the most common used) have no samples, no blogs, no documantation with - AngularJS ? 

Currently, there is no way to make a Mobile Application (SPA) search engine friendly. You cannot use the "alternate" and "canonical" tags, since the SPA page is only loaded once. And you can't use Google's suggested #! syntax, since Kendo only supports the # syntax. So there is basically no way to get a Kendo Mobile website indexed properly.

Some animations for Kendo view transitions in the Web UI would be awesome. SPA's are missing that nice fade or slide between view switching. 

Add a small nanoscopic progress bar featuring realistic trickle animations to convince your users that something is happening. This would be perfect for Turbolinks, Pjax, and other Ajax-heavy SPA's.
