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.

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.

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. 

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 ? 

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

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

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.

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.
